Rock mechanics is a subdiscipline within applied geology, geological engineering, and mining engineering focused on the physical mechanics of rock with applications in both dynamic structural geology and in engineering. An understanding of rock behavior requires proficiency in engineering mechanics, material properties and physics, and engineering geology, including structural geology. Rock mechanics may be considered with soil mechanics as end members of geomechanics. Rock is a natural material with substantial ranges in material properties: strong or weak, stiff or highly deformable, ductile or brittle, and durable to easily disaggregated and weathered. In the lower end of the strength range, rock will approach soil-like behavior.
Definition and Subject of the Discipline. Nature of the discipline and interdisciplinary connections. Discontinuity and granularity. Multicomponent structure. Mechanical Models of Rocks and Soils. Description of the models. The concepts of rheology of a continuum.

Civil and Environmental Engineering. Brittle Fracture Micromechanics. Rock Mechanics: problems, key concepts and approaches, fields of application. Engineering geology: Glacial movement and geological impact.
Soil mechanics is a branch of soil physics and applied mechanics that describes the behavior of soils. It differs from fluid mechanics and solid mechanics in the sense that soils consist of a heterogeneous mixture of fluids usually air and water and particles usually clay , silt , sand , and gravel but soil may also contain organic solids and other matter. Soil mechanics is used to analyze the deformations of and flow of fluids within natural and man-made structures that are supported on or made of soil, or structures that are buried in soils. Principles of soil mechanics are also used in related disciplines such as geophysical engineering , coastal engineering , agricultural engineering , hydrology and soil physics. This article describes the genesis and composition of soil, the distinction between pore water pressure and inter-granular effective stress , capillary action of fluids in the soil pore spaces, soil classification , seepage and permeability , time dependent change of volume due to squeezing water out of tiny pore spaces, also known as consolidation , shear strength and stiffness of soils. The shear strength of soils is primarily derived from friction between the particles and interlocking, which are very sensitive to the effective stress.
Because successful designs start with good ground, soil, and rock data, understanding rock mechanics in response to the force fields of their environment is important. As mines and infrastructure projects continue to advance into more difficult territory where excavations are larger, mines are deeper, and grades are lower, project requirements are becoming more complex. The highest levels of theory, observation, and expertise must work together to create the safest, most innovative rock-mechanics solutions in mining and energy.
The first issue of the journal was released in , under the name Solos e Rochas. In , the Brazilian Association for Soil Mechanics and Geotechnical Engineering took over the editorial and publishing responsibilities of Solos e Rochas, increasing its reach. In , the journal acquired the status of an international journal, being since then published by the Brazilian Association for Soil Mechanics and Geotechnical Engineering and Portuguese Geotechnical Society under the title Soils and Rocks. The aim of Soils and Rocks is to publish and disseminate basic and applied research in Geoengineering. Soils and Rocks publishes original and innovative peer reviewed articles, technical notes, case studies, reviews and discussions in the fields of Soil and Rock Mechanics, Geotechnical Engineering, Engineering Geology and Environmental Engineering.

Он же вас ненавидит. - Он позвонил и предупредил, что заканчивает работу над алгоритмом, создающим абсолютно стойкие шифры. Я ему не поверил. - Но зачем он вам об этом сообщил? - спросила Сьюзан. - Хотел предложить вам купить этот алгоритм. - Нет. Это был шантаж.
Все еще темно? - спросила Мидж. Но Бринкерхофф не ответил, лишившись дара речи. То, что он увидел, невозможно было себе представить. Стеклянный купол словно наполнился то и дело вспыхивающими огнями и бурлящими клубами пара. Бринкерхофф стоял точно завороженный и, не в силах унять дрожь, стукался лбом о стекло. Затем, охваченный паникой, помчался к двери. - Директор.
