ABSTRACT
Laboratory of geodynamics in the "Institute of Ionosphere" actively pursuing researches of the earth surface movements, geological, geophysical and geodynamic features of the structure of the crust and lithosphere in seismic regions, and conducts continuous monitoring due to dramatically impact of the cut on top of soil as a result of intensive constructions and medium altitude objects. The new approaches were used to the analysis of the strength and stability of the "soil-structure" system. High-rise building creates a lot of stress, penetrating to the depth and covering large volumes of soil. Daylight weak and watered soils limit state leads to the accumulation of irreversible deformation and, as a consequence, significant precipitation of the building. As a result of heterogeneous distribution of strains cause dangerous slopes instability for tall buildings. From the standpoint of the need for setting geodynamics work is dictated by the fact that Almaty is located in the submontane trough between the Kazakh Shield to the north and orogens of Northern Tien Shan . Submontane trough is part of the trough base of the crust and currently continues to be formed. Consequence of this process is a network of faults, traceable and within the city boundaries. Displacement amplitude for some of them is reaching hundreds of meters. Thus, a network of young major faults can significantly determine the strain distribution in the thickness of the crust within the city boundaries.
