This volume contains the edited texts of the lectures and written discussions prepared for the NATO sponsored Advanced Study Institute (ASI) on "Numerical Methods in Geomechanics" promoted by the University of Minho, Braga, Portugal and held at Vimeiro Hotel (Torres Vedras) - August 24 to September 4, 1981. The object of the NATO-AS I has been to gather, as lecturers ,a wide range of scientists and engineers specialized on the above branch of knwoledgement in order to cover the whole variety of approaches for the solution of the set of problems concerning Geomechanics.

The role of field measurements in risk assessment and the control of natural geohazards, in engineering design, construction and operation of engineering facilities has grown in the past and will undoubtedly grow in years to come with ever increasing demands on the engineering skills of people involved in these activities. It is therefore necessary to give those interested in instrumentation and measurements an opportunity to meet regularly to exchange ideas and experiences and to stimulate further advancement within field instrumentation.

The Proceedings of EUROCK 2010 is a collection of 6 keynotes and 193 technical papers accepted by the symposium. As an annual European regional event of the International Society for Rock Mechanics (ISRM), EUROCK has been a major exchange and discussion platform for the international rock mechanics community. Rock mechanics in Europe has been undergoing some major transformation during the last two decades. The reduction of mining activities in Europe affects heavily on rock mechanics teaching and research at universities and institutes. At the same time, new merging activities, notably, underground infrastructure construction, geothermal energy development, radioactive waste and CO2 repository, and natural hazard management, are creating new opportunities of research and engineering. Rock mechanics today is closely associated with, and indeed part of, construction, energy, and environmental engineering.

There has been very positive feedback from practicing engineers, who need a “go to’’ book, and who have suggested various additions. This encouragement now results in this 2nd edition which uses the similar format of summary data tables and expands the book with additional tables as well as some corrections and additional notes to the tables of the 1st edition.
This book is is principally a data book for the practicing Geotechnical Engineer and Engineering Geologist, which covers:

In this chapter, minimal prerequisites not only for classical mechanics but also for physics, in general, are introduced. Physical dimensions, SI base units, SIderived units, and significant figures are discussed. Four coordinate systems, Cartesian coordinates, plane polar coordinates, cylindrical coordinates, and spherical coordinates are concisely shown. The coordinate transformation, which will be used in later chapters, is discussed. A Taylor series expansion is often used in physics, so that it is precisely explained. <...>

Россия занимает первое место в мире по объему разведанных запасов кимберлита, основная часть которых сосредоточена в коренных месторождениях, расположенных в районах алмазоносной провинции Республики Саха (Якутия).

В книге приведены сведения о комплексе свойств горных пород и углей глубоких горизонтов Кузбасса, полученных при изучении Прокопьевско-Киселевского месторождения. Основное внимание уделено прочностным и деформационным параметрам в связи с проблемой освоения больших глубин н необходимостью оценки поведения пород в различных горно-геологических условиях. В работе приводятся сведения о инженерно-геологических условиях формирования прочности, деформируемости и ползучести горных пород и углей. Предлагается комплексная оценка свойств пород на основе вдавливания плоского штампа, обосновываются теоретические и физические возможности метода. Анализ обширного экспериментального материала ведется на основе расчленения пород по основным структурам; рассматривается возможность использования физико-механических свойств пород при оцшіке горно-геологических явлений.

Монография рассчитана на научных работников, специалистов в области горной механики и проектировщиков

Современные тенденции роста объемов производства в технологических отраслях, требующих использование цветных металлов, создают потребность в интенсификации добычи руд, в том числе медно-никелевых. Интенсификация темпов отработки запасов обуславливает увеличение глубины ведения горных работ, в результате чего повышается вероятность реализации геомеханических рисков.

The past three decades have seen a remarkable proliferation in the volume of literature devoted to geotechnical and foundation engineering. There are now a vast number of journals that address these subjects, and many conferences annually produce a welter of papers of variable quality. The undergraduate student is insulated from this plethora of information by curricula that usually follow a well-trodden path and which cover the basics of soil mechanics and engineering mechanics and which employ texts that have been tried, tested and refined over the past 50 years.

При ведении горных работ как открытым, так и подземным способом, негативным фактором является тенденция усложнения горнотехнических и горногеологических условий. Интенсивность горных работ, воздействие тектонических напряжений, а также наличие разного рода и масштаба разломных структур требуют заблаговременного учета и анализа напряженно-деформированного состояния (НДС) массива горных пород при геомеханическом обосновании и проектировании горных работ.
