Brazilian Symposium on Rock Mechanics – SBMR 2018

The most important geotechnical meeting in Brazil will be held in August 2018, bringing together five major thematic events, including the VIII SBMR - Brazilian Symposium on Rock Mechanics. Also in this edition, the SBMR consolidates itself as a specialized conference of the ISRM and aims to congregate professionals and students of rock mechanics in both national and international spheres, attracting especially participants from South America. The chairman of the event is Prof. Lineu Azuaga Ayres da Silva, president of the Brazilian Rock Mechanics Committee (CBMR). The main committee of the event is composed by the CBMR board members: Dr. Vivian Marchesi (vice-president of CBMR), Prof. Sergio Fontoura (general secretary of the CBMR and vice-president of ISRM for South America), Prof. Carlos Emmanuel Lautenschläger (executive secretary of CBMR) and Profª Anna Luiza Ayres da Silva (treasurer of the CBMR).

The event will take place between August 28 th and September 1 st 2018, in the city of Salvador, Bahia (Bahia Othon Palace Hotel). In parallel to the SBMR, four other events will take place: COBRAMSEG (Brazilian Congress of Soil Mechanics and Geotechnical Engineering), SPD (Pan-american Symposium on Landslides), Geojovem (Brazilian Symposium of Young Geotechnical Engineers) and Luso-Brasileiro (Luso-Brazilian Congress of Geotechnical Engineering). The central themes of the events are aligned with urban development, which is the theme of SBMR 2018: "Rocks Engineering on Urban Development".

The SBMR technical committee is completing the abstracts evaluation phase, and in this edition SBMR has more than 100 submissions distributed in the following subjects: Underground Excavations, Stability of Rock Slopes, Foundations of Dams and Rock Masses, Field and Laboratory Investigations, Rock Mechanics for Petroleum Engineering, Computational Modeling and Geosciences applied to Rock Mechanics. In addition to the technical sessions, there will be two plenary sessions related to rocks at the event. One of them is already defined, and will be proffered by Prof. Sergio Fontoura, on the subject of rock mechanics in petroleum engineering, addressing the necessary conditions for the success of a project.

In addition to the technical program, the 3rd edition of RockBowl Brazil will also take place within the Symposium. RockBowl is a very successful game, consolidated in the geotechnical community since the last two editions of the SBMR. Organized by CBMR, the game is sponsored by Geobrugg. The prize for the winning team will be a sponsorship to represent Brazil in the international edition of RockBowl, during the International Congress of Rock Mechanics in 2019.

The eighth edition of the SBMR is special for CBMR because it is the largest national rock event before ISRM 2019, which will be held in Foz do Iguaçú in September 2019. The organizers of the symposium are committed to mobilising the Brazilian geotechnical community to participate in the most important international event of rock mechanics.

Franz Pacher 1919-2018 - In memory of an outstanding engineer and man

P rofessor Franz Pacher, pioneer of rock mechanics and modern tunnel construction, has passed away in his hometown Salzburg on the 3rd of March 2018 at the age of 98.

Franz Pacher was born in 1919 in Mittelsuchau, now Prostřední Suchá in the Czech Republic. He grew up in Graz, Austria, where he also completed his schooling, military service and, between 1939 and 1943, his study of civil engineering at the Graz University of Technology. From 1943 to 1945 he worked as a scientist in the hydraulic engineering department. From 1945 to 1952 he was a construction manager for hydroelectric power plants in Austria.

Franz Pacher moved to Salzburg in 1952 and started work in Dr. Leopold Müller’s Office for Geology and Civil Engineering. 1952 was also the first year in which a colloquium to improve the mutual understanding of geology and construction was held, albeit the number of delegates did not approach 1000 as it does today, and Dr. Müller’s living room was an adequate venue. Rapid advances in the field of rock mechanics were made in the following years, in which Pacher und Müller played decisive roles. In parallel, collaboration with L. v. Rabcewicz lead to the development of modern tunnelling in the form of the “New Austrian Tunnelling Method”.

Particular achievements of Pacher are in the area of fundamental research, for example the definition of planar and volumetric proportions of discontinuities and the ground reaction curve. In a 1964 publication, Pacher demonstrated for the first time a method for prediction and graphical representation of the interaction between ground pressure and tunnel support loading (the Pacher-Fenner curve). This was based on measurements of deformations and led to the development of the convergence-confinement method. In 2009 Pacher extended this representation to a diagram showing the time-dependency of both ground pressure and deformation.

Franz Pacher was a founding member of the International Society for Rock Mechanics (ISRM) in 1962 and the Austrian Society for Geomechanics in 1968, both in Salzburg. He was also leader of an internationally active engineering company, a researcher and teacher at the Technical Universities of Munich and Vienna and an honorary member of several institutions in the fields of rock mechanics and tunnel construction. Furthermore, his 45-year career gave us 60 lectures and publications. Further information on Franz Pacher and the founding of the ISRM is available in an interview with him on the 50th anniversary of the founding of the ISRM ( ).

We will always hold this outstanding engineer and man in great respect and wish that he may be an example to us and to future generations.

In memory of Richard Z.T. Bieniawski

Prof. Richard Z.T. Bieniawski, died on 11 December 2017 at his home. He was born in 1936, in Krakow, Poland. He was one of the most prominent and influential rock engineering personalities of the 20th century.

Prof. Bieniawski was trained as a naval architect and marine engineer in Poland, graduated in South Africa as mechanical engineer and obtained a doctorate in mining and tunnel engineering. He taught for 20 years at the Pennsylvania State University and retired on his 60th birthday to Prescott, having become Visiting Professor of Design Engineering at the University of Cambridge, England.

In the ISRM, he was chairman of the Commission on Testing Methods from 1972 to 1979 and Vice President for Africa from 1974 to 1979.

As two who have been to ISRM conferences for a long time, and therefore have known Dick Bieniawski for more than half his life, and during a bigger proportion of our own, it was with sadness we recently heard the news of his death on December 11, 2017.

His enthusiasm for life and work - seemingly at all times - was a foolproof camouflage of the fact that he had a long life, and was truly a senior and respected colleague. Starting in South Africa as a mechanical engineer, where he obtained a PhD in mining and tunnel engineering, he has been through his life a teacher and an engineer.

It is true perhaps, but misleading of his multi-faceted contributions to education, to rock mechanics and to rock engineering, that he is best known for his own RMR rock mass rating, which was a prime member of the 1972, 1973 and 1974 independently developed rock mass classification methods.

It is of interest to underline here that these classification methods miraculously developed almost simultaneously, if we look at the longer time-scale. RMR has of course provided healthy competition for Q, and gave a flying start for GSI.

Dick's book on rock mass classification methods of 1989, Engineering Rock Mass Classifications - A Complete Manual for Engineers and Geologists in Mining, Civil, and Petroleum Engineering, is one of the most cited texts in rock engineering.

However, how could Dick’s contributions to rock mechanics and rock engineering, during his first steps in the discipline, be neglected? The invaluable PhD thesis on the Mechanism of the Brittle Fracture of Rock in compression and tension is a remarkable sign of Dick’s ability to couple theory and practice.

The precious contributions of Dick Bieniawski to rock engineering in mining and tunneling are also to be reminded, as well demonstrated with his books on Strata Control in Mineral Engineering of 1987 and on Rock Mechanics Design in Mining and Tunneling of 1989.

The use of consistent design methods in rock engineering has always been Dick’s concern. This is well demonstrated in the books on Tunnel Design by Rock Mass Classifications of 1990 and on Design Methodology in Rock Engineering of 1992, always complemented with important case histories.

A tribute to Prof. Don Deere, 1922-2018

Regrettably Prof. Don U. Deere left us on January 14th at the age of 95. He had hardly recovered from a fall a few months earlier. His passing, however, leaves very good memories for his former students, assistants, colleagues and clients. Five years ago, when he was celebrating his 90th birthday, we were invited by his son Don W. Deere and daughter to Gainesville, Florida, to a memorable ceremony, while Prof. Deere was still very active. His last years after he recovered almost totally from a stroke were spent golfing, dancing, etc. at his glamourous retirement resort.

He represented a very important milestone for Engineering Geology and Rock Mechanics in his activities at the University of Illinois, Champaign-Urbana Campus, in the 60s and 70s. Together with Prof. Ralph Peck, they led and pioneered Geotechnics and Rock Mechanics in the USA. His area of expertise covered Civil Engineering (Ph.D), Mining (B.S.) and Geology (M.Sc.). My own impression is that Prof. Deere was a man who was very kind and respectful of his students and colleagues whom he encouraged the most. Moreover, he was a man who knew how to utilize the potential of his assistants to make them grow together with him. This resulted in a formation of a group of very talented colleagues, such as Ron Heuer, Alfred J. Hendron, Ed Cording, Frank Patton, and later Gabriel Fernandez, among others who were not of my time. Among his former students, you can find many engineers and geologists who reached senior and influential positions, like Andy Merritt (his consulting partner), Ray Miller, Harvey Parker (President of ITA), Jim Coulson (Chief Engineer at TVA), Ray Benson and Bob Conlon (Both Geotechnical Department Heads at Acres), Brian Sinclair, Sergio Brito, Alan Smallwood, Jim Gamble, Alberto Nieto, Jim Mahar and many others including the author of these lines. After many years at the University of Illinois, he moved to the University of Florida where he could devote more time to his consulting practice.

He was a recognized expert in Engineering Geology and Rock Mechanics and has the great merit of integrating Geology in Geotechnical and Geomechanical projects. He consulted on numerous dams, mining, tunnels and other underground projects for the US government, contractors and design engineering companies all over the world. Many of these projects involved precedent structures such as the Churchill Falls hydroelectric project in Labrador, Canada and the World Trade Centre in New York city. He also acted as a member of the Board of Consultants in many other large projects around the world. In Brazil he made very important contributions as a member of Board of Consultants for the following hydroelectric projects: Itaipu, Água Vermelha, Sobradinho, Itaparica, Paulo Afonso, Itumbiara, Sao Felix, Altamira and others. His first mission in Brazil was to help me on the design of the final slopes of the Cauê Open Pit Mine, in 1972.

His experiences in the field became teaching material for his classes. He wrote and co-authored numerous papers and was, of course, the inventor of the rock mass assessment tool, the RQD. Together with Giovanni Lombardi, he invented the GIN method of grouting. He was Chairman of the US Nuclear Waste Technical Review Board. He was the President of the Commission on Standardization of Laboratory and Field Tests of the ISRM from 1968 to 1973. He received numerous distinctions throughout his career including being elected to both the National Academy of Engineering and the National Academy of Sciences. He was also a consummate joke teller.
