No. 51 - September 2020

Message from the President

Dear Rock Mechanics Colleagues,

COVID-19 is still around, and each country is handling its situation differently. Things are different than they were at this time last year, and unfortunately, in terms of the effects of pandemic, there is still uncertainty about the future in the entire world. Whatever the conditions are, all societies, like ISRM, should continue to provide continuing activities. With the world being turned upside-down by COVID-19 face to face activities are rather difficult, video conferences, webinars and similar tools have become the new normal. Therefore, in these difficult days, ISRM also began to pay more attention to the use of these techniques for the communication with its members and continuation of its activities.

Since April, the Board continued to work on the planned issues and became in constant dialogue with the organizing committees of the ISRM events planned in 2020. But the cancellation of EUROCK2020, the international 2020 ISRM Symposium, became inevitable and a difficult decision made by its Organizing Committee due to the current COVID-19 pandemic and of the strong restriction to travelling. As ISRM, we would like to show our deep appreciation for the kind work of the Organizing Committee and of the Norwegian National Group for Rock Mechanics, who did everything they could to go ahead with the organization of EUROCK2020. The Organizing Committee and ISRM agreed that more than 200 peer-reviewed papers presented to EUROCK2020 will be published in the ISRM’s digital library on the platform, subject to the authors’ consent.

The 11th Asian Rock Mechanics Symposium, ARMS11, has also been postponed to 2021 due to the pandemic to 21-25 October 2021 and it will be held in Beijing, China. One of the two ISRM Specialized Conferences, 5th Symposium of the Macedonian Association of Geotechnics (Ohrid, Macedonia) was postponed to 10-12 June 2021. However, the second ISRM specialized Conference “CouFrac” 2020, to be held between 11-13 November 2020, in Seoul, Korea, was not postponed and has turned into a fully virtual conference with simultaneous offline meetings. Due to COVID-19 crisis, the special session in honor of Prof. Pierre Habib, the ISRM Past President, in Paris, was also postponed to 2021. The exact date of this session will be announced later on and ISRM will also be represented by a Board member in this session. I congratulate the initiative of the Bolivian Geomechanics Association to promote series of webinars on rock mechanics with participation of eight lecturers between 24 September and 16 October 2020. The National Group of Bolivia is a growing society and its Board is very enthusiastic and this activity is related to the celebration of the 10 years anniversary of this group.

31st ISRM online lecture by Prof. Frederic Pellet

For the 31st ISRM Online Lecture the ISRM invited Prof. Frederic Pellet. The title of the lecture is “Damage and Time-Dependent Behavior of Rocks in Underground Construction”.

The lecture was broadcast on 24 September and will remain available in the online lectures dedicated webpage .

Dr. Pellet is a professor of geomechanics and rock engineering in INSA University of Lyon. He obtained his BSc in civil engineering at the Technical University of Geneva, Switzerland, and his MSc in geotechnical engineering at the University of Grenoble, France (1986). After a few years working for consulting companies in different fields, such as dam engineering and hydroelectric projects, he joined the Ecole Polytechnique Fédérale de Lausanne, Switzerland, where he prepared a doctoral thesis on rocks reinforcement. His thesis received the prize of the French Tunneling Association (AFTES) in 1993.

After another period spent in industry, Dr Pellet became an academic in 1996; first as an associate professor at the University of Grenoble (Lab 3SR) and then, in 2009, as a full professor at the University of Lyon (INSA). His scientific approach is based on a combination of experimental approaches and numerical modeling to enable risk analyzes. It has led him to study various subjects related to time-dependent behavior of rocks such as large transport infrastructures (deep alpine tunnels), underground storage of radioactive waste in close relationship with the French Institute for Radioprotection. Today, he mainly focuses on the exploitation of deep geothermal energy and delayed induced seismicity.

Dr. Pellet has collaborated with numerous institutions such as the Massachusetts Institute of Technology (United States), McGill University and the University of Sherbrooke (Canada) Mines ParisTech (France). He has also worked for several companies in the civil engineering and petroleum industry. At the same time, he is the author of more than 120 technical articles and book chapters on rock engineering and has delivered 35 invited addresses or lectures at national and international conferences. He is on the editorial boards of several international journals.

Between 2011 and 2016, Dr Pellet served as Vice-President of the ISRM for Europe and President of the French national group. Since 2010, Dr. Pellet has worked in several countries on various review committees, providing an independent geotechnical study on major civil engineering projects.

Pierre Duffaut 1924-2020

We regret to inform you that Pierre Duffaut passed away on September 11th in Paris. He was an esteemed colleague and a friend so it is with a heavy heart that we share this sad piece of news.

Pierre Duffaut graduated from the Saint-Etienne School of Mines (France) after which he joined the EDF (French Electrical Board) geological department in 1947. He worked there with a team of engineering geologists, carrying out field missions in the French Alps each summer. He supervised the construction of a dam in the French Pyrenees for two years, during which time the Malpasset dam disaster took place, in 1959.

Pierre Duffaut was already interested in hydropower reservoirs, underground works and slope stability so he immediately understood the necessity of rock mechanics in dam engineering. From this time onwards, he always argued for a combined approach between geology and rock mechanics, using his talents in geological observation and his knowledge of dam construction and design. In 1977 Pierre Duffaut moved to the BRGM (French Geological Survey) as a Head of Geotechnical Department.

Retired in 1981, he never stopped working, teaching, consulting and writing numerous publications, over 200. He launched and coordinated the first volume of the French Manual of Rock Mechanics. Visionary in the use of underground space, he imagined an underground city and promoted the development of large caverns.

He gave the 3rd ISRM Online Lecture on "Rock Mechanics - Lessons from Dams", a memorable lecture that you can watch here: .

Pierre Duffaut was passionate about sharing his knowledge: he had a particular talent in engaging the next generation of engineers. His constant sense of humour, smile and laugh were infectious. With his passing, a piece of the early stages of rock mechanics passes with him. He will be dearly missed by the ISRM and French community of rock mechanics, as well as by the many friends he had.
