Добрый день, Коллеги. Важное сообщение, просьба принять участие. Музей Ферсмана ищет помощь для реставрационных работ в помещении. Подробности по ссылке
The principle features of the Theological processes in rock salt are plasticity, creep and fracturing. A treatment of this features involves geotechnical measurements (laboratory, in-situ), theoretical investigations (continuum mechanics), and microphysical considerations (dislocations, grain structure). The knowledge of the thermo-mechanical behavior of rock salt is an essential part of any assessment of the stability of underground openings for waste disposal purposes. Each, an assessment and the evaluation of the integrity of the geological barrier can only be performed by calculations with validated geomechanical models. Some results of these calculations for the preliminary repository design of the Gorleben site and the research mine ASSE II are given. <...>
«Инструкция по составлению проекта разработки месторождения твердых полезных ископаемых» может служит нормативным документом при составлении проектной документации для разработки месторождений твердых полезных ископаемых подземным, открытым, геотехнологическим или комбинированным т.е. последовательным сочетанием подземного и наземного, способами.
The book sets out to present a state of practice of the geotechnical engineering of embankment dams and their foundations and the geotechnical engineering of the foundations of concrete dams. It assumes that the reader is trained in Civil Engineering or Engineering Geology, with knowledge of soil and rock mechanics.
The use of shallow geothermal energy has increased enormously over the past ten years. As the number of geothermal energy installations has risen, so has the number of technical developments in the field. There have been cases of damage in connection with the construction and operation of geothermal energy systems which have attracted much attention in the media. In particular, the cases of damage that have become public show that drilling to depths of several hundred metres is a technical activity that calls for responsible procedures in the sense of quality-assured design, construction and operation of the systems. Avoiding damage caused by shallow geothermal energy installations is a top priority for sustainable geothermal energy uses, especially when bodies of groundwater have to be protected against adverse effects.

The discrete element method can effectively simulate the discontinuity, inhomogeneity, and large deformation damage of rock and soil. It is widely used in both research and industry. Based on the innovative matrix discrete element computing method, the author developed the high-performance discrete element software MatDEM from scratch, which can handle millions of elements in discrete element numerical simulations. This book introduces the basic structure, modeling methods, numerical calculation processes, post-processing, and system functions of MatDEM, which applies the basic principles and algorithm of the discrete element method. It also presents several examples of applications in geological and geotechnical engineering, including basic geotechnical engineering problems, discrete element tests, three-dimensional landslides, and dynamic and multi-field coupling functions. Teaching videos and the relevant software can be accessed on theMATDEM website (http://matdem.com).
The book will serve as a useful reference for research and engineering staff, undergraduates, and postgraduates who work in the fields of geology, geotechnical, water conservancy, civil engineering, mining, and physics.
In terms of both volume and mass, waste dumps associated with large open pit mines are arguably the largest manmade structures on Earth. Their footprints typically exceed the aerial extent and their heights often rival the depths of the open pits from which the material used to construct them is derived.
Дается краткая характеристика особых условий строительства в карстовых районах. Рекомендуется оценивать устойчивость территорий и производить расчеты зданий и сооружений по данным о среднегодовом количестве провалов, приходящихся на единицу площади, и графикам распределения провалов по их величине. Рассматриваются особенности составления схем районной планировки, генеральных планов городов и проектов детальной планировки. Даются рекомендации по определению характера застройки территорий в зависимости от их устойчивости и излагаются основные требования к жилищному и гражданскому строительству в карстовых районах. Приводятся рекомендации по выбору конструктивных схем и реиений промышленных зданий и сооружений. В приложениях дается обоснование рекомендуемого характера застройки территорий и излагается метод расчета ленточных фундаментов как одного из рекомендуемых средств защиты от карстовых провалов ограниченного размера. Рекомендации предназначены для инженерно-технических работников проектных и изыскательских организаций.
