The fi rst three parts of the section address the development of soil mechanics and geotechnical engineering as a distinct discipline over the past 80 years or so. Chapter 2 Foundations and other geotechnical elements in context - their role explains the importance of foundations and structures built in or of the ground within civil engineering and construction, and the need for a formal and holistic geotechnical engineering design process. Chapter 3 A brief history of the development of geotechnical engineering gives a history of the development of geotechnical engineering at the borderline between science and art, with the latter defi ned by Terzaghi in 1957 as a ‘mental processes leading to satisfactory results without the assistance of step-for-step logical reasoning’. This is refl ected in the ‘geotechnical triangle’, described in Chapter 4 The geotechnical triangle, which emphasises the essential elements of successful geotechnical engineering as understanding the ground, material properties and relevant precedence (well-winnowed experience), connected by an appropriate model for analysis. <...>

The Italian Conference of Researchers in Geotechnical Engineering—CNRIG— reached this year its seventh edition, three years after the successful conference held in Bologna in 2016. The conference was promoted by the National Group of Geotechnical Engineering (GNIG; http://www.gnig.it/) and hosted by Politecnico di Milano (https://www.polimi.it/) at the campus in Lecco (Polo Territoriale di Lecco, http://www.polo-lecco.polimi.it/en). The conference provides an important opportunity to share scientific advances, innovation, and application in geotechnical engineering and is becoming a traditional event for the Italian geotechnical community. <...>

International Scientific-Technical Conference «Geotechnics Fundamentals and Applications in Construction: New Materials, Structures, Technologies and Calculations» (GFAC 2019) was held by Saint Petersburg State University of Architecture and Civil Engineering 6–8 February 2019. Its aim was devoted to enable the interactive exchange of state-of-the-art knowledge and to bring together leading academic scientists, researchers and scholars in the domain of interest from around the world. The Conference provided a unique forum for prominent researchers and young talented specialists to present the latest research findings, emerging technologies and directions in geotechnics, soil mechanics, foundation engineering and all related construction spheres <...>

Problems of slope stability, instability, and the associated mass movement processes of slope failure, represent research themes common to both geotechnical engineers and geomorphologists, although their perspectives clearly differ. While the engineering concern is generally site specific and limited by project design-life considerations to time periods of less than 100 years, for the geomorphologist longer term slope stability and slope evolution, involving a mixture of slope processes operating over tens of thousands of years, constitute a major area of enquiry (e.g. Kirkby, 1984).

Современные цифровые технологии создания горно-геологических информационных систем первоначально использовали геологи для трехмерного геологического моделирования месторождений и подсчета запасов руды. Позднее их стали применять горняки для проектирования, планирования и оперативного (маркшейдерского и пр.) сопровождения горных работ. Логическим продолжением данной тенденции цифровизации горного производства явилась практика создания геомеханической модели рудника. Она включает в себя информационные оболочки: геолого-структурную (распределение в массиве разных типов пород, их изменений – выветривание, метасоматическая проработка, каркасы тектонических разломов, сетка трещин), рейтинговых оценок качества массивов и их механических свойств.
В необходимых случаях добавляется гидрогеологическая компонента модели (распределение уровней подземных вод, порового  давления в пространстве). <...>
