АНАЛИЗ УСТОЙЧИВОСТИ И ДИНАМИЧНОСТИ РЕЛЬЕФА ГОРОДА МОСКВА

Abstract

The map of earth's surface deformation is compiled for the territory of the city. Deformations are caused by natural factors - frost heave, landslides, karst, suffusion, recent crustal movements and by anthropogenic factors - compacting of technogenic grounds, subsurface constructing, technogenic watering, static and dynamic loads by edifices and transport, water pumping etc. Total surface deformations reach their maximum in the central parts of the city, where the velocity of the subsidence consists 1-2 mm/year and the amount of buildings deformed reaches 30-50 per km2. In the peripheral districts the subsidence is less than 1 mm/year and damaged communications and buildings don't exceed 1-6 per km2. The dividing of the city into districts with different stability to dynamic (including seismic) forces is fulfilled. The earthquake of I = 3-4 may be intensified up to I = 5-7 in the unstable areas.
