Update on the VII South American Congress on Rock Mechanics, an ISRM Regional Symposium
Lima, Peru, 2-4 December 2010

The Peruvian Society of Geo-engineering is organizing the 7th South American Congress on Rock Mechanics, which will take place in Lima, Peru, from December 2 to 4, 2010 and will be co-sponsored by the International Society for Rock Mechanics (ISRM) and the Peruvian Institute of Mining Engineers (IIMP).

The aim of this forthcoming congress is to offer a space where the world's most respected experts in the field of rock mechanics can share their experiences with their South American colleagues and discuss with them the most recent advances in this important discipline of engineering.

Most South American countries share the challenge of having to design and build a variety of complex engineering works (roads, tunnels and hydro-power stations) within the Andes, as well as mining the vast mineral resources hosted by this important mountain range, which means that civil and mining engineers working in this part of the world have been able to accumulate a rich and valuable technical experience in surface and underground engineering in rugged and difficult rock environments.

The themes of the Congress are:

  • Design of underground excavations
  • Open pit design
  • Geotechnical information and site characterization
  • Perfomance and Monitoring of excavations
  • Geotechnical modelling

A total of 45 abstracts were approved and 30 will be selected for presentation. Several keynote lectures will take place. The following speakers are already confirmed: E.T. Brown, J.A. Hudson, X.T. Feng, N. Barton, R. Pakalnis, C. Carranza Torres and L. Lorig.

Registration for the Congress is now open. If you are interested in participating, you are kindly invited to contact the Organizing Committee at eventos@iimp.org.

FedIGS developments

As many of you will know, a Federation of International Geo-engineering Societies (FedIGS) was established recently, the three constituent Societies being the ISRM, the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE), and the International Association for Engineering Geology and the Environment (IAEG). The intention of FedIGS is to enhance communication between the three Societies in areas of mutual interest. However, the configuration and style of the originally formed FedIGS turned out to be inherently cumbersome and functionally inflexible.

Accordingly, the three current Society Presidents, John Hudson of the ISRM, Jean-Louis Briaud of the ISSMGE, and Fred Baynes of the IAEG made a series of agreed recommendations for re-configuring FedIGS to a leaner more effective Federation. These included the elimination of fees, a reduction in the number of Joint Technical Committees (JTCs), and a reduction in Liaison Committee members. These recommendations were adopted by the FedIGS Board at a meeting in London, UK, on 28 May 2010. The intention is that, while retaining the basic thrust of FedIGS in enhancing communication between the constituent Societies, it will now be a sleeker and more informal organisation.

To take us forward with this new FedIGS configuration, I am pleased to report that our previous ISRM President, Nielen van der Merwe, is now the Chairman of FedIGS. He has invaluable related experience, both with the ISRM and with the development of FedIGS. Thus, I am now confident, given the FedIGS reconfiguration, that the ISRM membership of FedIGS is indeed ‘a good thing’ and will enable us to follow up any required inter-Societal initiatives rapidly and effectively.

A plan to develop a deep underground science and engineering laboratory (DUSEL) is taking shape at the former Homestake Gold Mine in Lead, SD.

The mine produced more than $38B of gold over its century-and-a-quarter lifetime and was the site of a Nobel Prize winning experiment that identified a deficit in the number of neutrinos produced by the Sun. The mine reaches to a depth of ~2500 m (~8000 ft) and is being dewatered and rehabilitated as the prospective home for experiments in astrophysics and particle physics, in biology, in geosciences and in engineering.

Physicists go deep primarily to escape the noise in their detectors produced by the interactions of the active detector material with the shower of particles created by cosmic-ray collisions in the atmosphere. The rock of the mine is a very effective shield for those particles and allows physicists to record and study weakly interacting particles such as neutrinos or WIMPs which are naturally traversing the Earth. These particles interact very rarely with matter and would be lost in the background in a surface detector. In fact their collisions with matter are so rare that all but one in ten-trillion pass clear through the Earth without a collision. But the chance of observing such events is increased as the mass, and thus size, of the subterranean liquid-filled detector is increased. Large and deep detectors are the desired standard and large caverns spanning 60m and at a depth of 1500 m are proposed – these pose unprecedented construction challenges.

Geoscientists and engineers are going deep to help in this effort, but also to explore the processes that shape our planet and to ensure good stewardship of the resources that sustain our existence. Proposed experiments are arranged in both observatories and as active mine-by, heating and fracturing experiments. These address questions related to the inner workings of the Earth’s crust and how we safely build unprecedented structures within it.

Experimental groups are currently evaluating the feasibility of a variety of experiments to better characterize the subsurface at all scales, to probe scale- and time-dependent effects in rock masses related to fracturing, the transport of fluids and the evolution of biota and to develop improved methods to define the response of structures and treatments in the subsurface.

This effort to establish a multi-disciplinary deep underground laboratory with the capacity to accommodate these and other frontier experiments for the next fifty years is being explored by the National Science Foundation and the academic community. Such experiments are the subject of multiple development efforts to explore their feasibility for such a laboratory, should the plan for DUSEL become a reality.

Landslide risk management concepts and guidelines

Slope instability occurs regularly in urban and remote areas throughout the world. These events often impact on infrastructure and have devastating impacts on people. This result has been recognised by many tiers of government and have led to the development of many landslide risk management guidelines.

In recognition of deficiencies and inadequacies in many of these guidelines, in 1999 the National Committee of the Australian Geomechanics Society set up a sub-committee to address these areas and to establish new guidelines to help practitioners carry out stability assessments in rock and soil using risk based rocedures. The most recent publication of the sub-committee can be found under the heading Landslide Risk Management 2007 at http://www.australiangeomechanics.org/resources/downloads/

EUROCK 2010 - a review

EUROCK 2010, the ISRM European Regional Rock Mechanics Symposium was held on 15-18 June 2010, on the campus of the Swiss Federal Institute of Technology Lausanne (EPFL), Switzerland. The theme of the symposium was “Rock Mechanics in Civil and Environmental Engineering” and the proceedings collects 198 papers including 5 keynotes.

One important mission of the EUROCK 2010 was to bring the rock mechanics community in Europe together, to exchange, to collaborate and to progress. This objective was well achieved by having 336 participants, from 26 countries in Europe and 17 countries/regions in other continents.


Welcome by the Swiss Alpine horn performance at the banquet reception in the Olympic museum.

EUROCK 2010 made consented effort to attract young rock mechanics professionals to the symposium, with a low registration fee. There were 95 young professionals (students and engineers) attended the symposium. The first EUROCK Award for the best paper by a young scientist/engineer was given at EUROCK 2010. Altogether 33 young authors participated the competition and the winner was Azania Mufundirwa and the runner-up was Matt Lato.

An open discussion on the future of rock mechanics in Europe generated sufficient interests among the delegates, towards a stronger rock mechanics community in Europe, by increasing the visibility of rock mechanics in teaching, research and engineering applications.

Corporate members' highlights - Suncoh Consultants Corporation

Suncoh Corporation is the general consultant in the civil engineering field in Japan. In the field of geological investigation we had worked the Akashi-Kaikyo Bridge (the world's longest three-span suspension bridge), the Seikan Tunnel (the world's longest undersea tunnel). Recently, we are researching the high-level radioactive waste and CCS (Carbon Capture and Storage) as a global environmental protection.

The many large earthquakes occur in the Japanese Islands which is located in the Circum-Pacific seismic zone and we predict the high event probability of large earthquakes. So we have to study the safety of ground and structure foundation considering influence of earthquakes.

We have developed new stiffen direct shear equipment to determine strength and deformation characteristics of rock joints. We apply these parameters to the numerical analyses which are Multiple Yield Model (MYM) for small deformation and Discontinuous Deformation Analysis (DDA) for large deformation.

As an example, we show the result of simulation of a rock collapse that occurred by the Mid Niigata Prefecture Earthquake in 2004(M=6.8) using MYM and DDA.

We examined the stability of rock slope during earthquake using the static and the dynamic analyses of MYM as a kind of a non-linear FEM considering rock joints to estimate of the potential of collapse before earthquakes. And we analyzed collapse modes during earthquakes by using DDA. URL:http://www.suncoh.co.jp/ (Japanese only).
