Analysis of the seismic stability of foundations according to laboratory soil tests

Abstract

Abstract Seismically hazardous areas are widespread on the territory of Russia. These are the North Caucasus, Altai, Sayan, Eastern Siberia, Kamchatka, Sakhalin. The issues of earthquake-resistant construction in difficult engineering and geological conditions, design in new earthquake-prone zones and construction in already developed territories are important aspects of the increasing intensity of development. Against this background, the problem of assessing the dynamic stability of soils becomes a priority task of modern soil dynamics and geotechnics. The article focuses on highlighting the main stages of the analysis of the dynamic stability of the foundations of structures of increased responsibility, taking into account complex geological conditions. The work contains the theoretical foundations of the methodology for assessing stability under dynamic loads, a description of laboratory equipment and test methods, the process of processing the experimental results. The study uses the results of assessing the dynamic stability of foundations obtained in the course of practical activities of the Scientific and Educational Center “Geotechnics” of the Moscow State University of Civil Engineering..
