The evaluation of rock mass excavation (i.e. its excavatibility) has become an increasingly important factor in the economics of civil engineering, particularly for road and motorway construction projects. The most common problem associated with rock excavation is the incorrect assessment of its fracture state. This can result in large delays to the programme with consequent claims and tends to reflect poorly on the service provided by the geotechnical professional. <...>

Proceedings of the 14th international conference of international association for computer methods and recent advances in geomechanics, Kyoto, Japan, 22–25 september 2014

Over the last half a century, constitutive models for geomaterials and numerical analysis methods have been well developed. Nowadays, numerical methods play a very important role in Geotechnical Engineering. The first pioneering conference was held at Waterways Experiment Station, Vicksburg, Mississippi, USA in 1972 under the leadership of Prof. C.S. Desai. Then, subsequent conferences were held in Blacksburg (USA) – 1976, Aachen (Germany) – 1979, Edmonton (Canada) – 1982, Nagoya (Japan) – 1985, Innsbruck (Austria) – 1988, Cairns (Australia) – 1991, Morgantown (USA) – 1994, Wuhan (China) – 1997, Tucson (USA) – 2001, Torino (Italy) – 2005, and Goa (India) – 2008. Now the conference is organized by IACMAG every three years. The last one, the 13th International Conference on Computer Methods and Advances in Geomechanics, was held in Melbourne, Australia in 2011. The 14th conference, here in Kyoto, was accepted at the Melbourne conference in 2011. This conference series is the main activity of the International Association for Computer Methods and Advances in Geomechanics founded in 70’s by Prof. C.S. Desai of the University of Arizona; the present president of IACMAG is Prof. J. Carter of the University of Newcastle. <...>

It is well known that numerical methods play a very important role in geotechnical engineering and in a related activity called “computational geotechnics”. The area that is covered by computational geotechnics is growing, in particular that which relates to the multiphase nature of geomaterials. This book is the second volume of Computational Modeling of Multiphase Geomaterials that was published in 2012 and provides recent progress in this area, i.e., the basic concept of the air–water–soil mixture, cyclic constitutive models, anisotropic models, non-coaxial models, gradient models, strain localization including compaction bands, dynamic strain localization, and the instability of unsaturated soils.

The European Regional Technical Committee (ERTC7) of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) and the Organizing Committee welcome all participants of the 9th European Conference on Numerical Methods in Geotechnical Engineering (NUMGE2018), held at the Faculty of Engineering of University of Porto (FEUP), in Porto, Portugal, from 25th to 27th June 2018.

The engineer designing such soil structures as embankments, dams, or building foundations should be able to predict the safety of these against collapse or excessive deformation under various loading conditions which are deemed possible. On occasion, he may have to apply his predictive knowledge to events in natural soil or rock outcrops, subject perhaps to new, man-made conditions. Typical of this is the disastrous collapse of the mountain (Mount Toc) bounding the Vajont reservoir which occurred on 9 October 1963 in Italy (Müller 1965). Figure 1.1 shows both a sketch indicating the extent of the failure and a diagram indicating the cross section of the encountered ground movement. <...>

В книге приведены сведения о механических свойствах горных пород, описаны способы испытаний пород и типовое оборудование. Рассмотрены теории прочности горных пород, механизм прочности неоднородных и трещиноватых структур, деформационные реологические свойства пород, а также ускоренные методы их определения. Большое внимание уделено обоснованию и изложению методики и техники лабораторных и натурных испытаний горных пород.

Книга рассчитана на инженерно-технических работников производства, научно-исследовательских и проектных институтов, преподавателей и студентов вузов горного и строительного профиля

It is important that research outcomes be disseminated in a useful form to the clients of the research, and to the community at large if appropriate. The research monograph is a traditional mechanism for reporting substantial bodies of research which, taken together, advance the field to a significant degree. In 1996 the JKMRC published two such monographs, on comminution and blasting, in a series on mining and mineral processing. The present volume continues the series.

The Symposium of the International Association for Computer Methods and Advances in Geomechanics (IACMAG) was held at the Indian Institute of Technology Gandhinagar, Gujarat, India, during the period 5–7 March 2019. Computer applications of geomechanics have been gaining much popularity from the early days of the International Conference on Numerical Methods in Geomechanics at Vicksburg in 1972, Blacksburg in 1976 and Innsbruck, Austria, in 1988. It was in that very context the IACMAG was established and it has been growing ever since with various stakeholders contributing significantly from different nations across the world. IACMAG aims at fostering multidisciplinary research and ideas pertaining to geomechanics with particular emphasis on integrating both the practical and the fundamental aspects. The field of geomechanics has evolved with time, and in this regard, IACMAG takes into account the need for judicious simplification of fundamental aspects of geomechanics with a proper amalgamation of theory and experimentation in order that they find their use in practical problems and challenges faced in the industry today. <...>

 Освоение горных и предгорных территорий Центральной Азии, строительство автомобильных и железных дорог на горных склонах и их подножиях, возведение гидроэлектростанций на горных реках неизбежно сопровождаются изменением установившегося природного равновесия горных склонов.
