Any process is determined by certain geological conditions and types of technogenic influences.
There is a variety of ways in which geological environment is subject to the urban impact. The static loads on thickness caused by weight of buildings and constructions are to be considered as the most widespread type of impact. Pumping-out of underground water is the other type of technogenic effect on geological environment. It causes the decreasing hydrostatic heads and static levels of underground water horizons. The disturbance of natural hydrodynamic conditions leads to the change of the stressed states of water-containing soils and, as a result, to the compression of rocks caused by depression craters.
