CONTAMINATION OF WATER-SATURATED SANDY-CLAY SOILS IN THE UNDERGROUND SPACE OF MEGALOPOLISES AND ITS CONNECTION TO BUILDINGS LONG-TERM STABILITY (THE CASE STUDY OF SAINT-PETERSBURG)

Dashko, R. E.; Lebedeva, Y. A.
Abstract:
The paper considers the main natural and technogenic factors forming the ecological state of the underground space and its influence on the long-term stability of buildings in such megalopolises as Saint Petersburg. Various contamination sources of Saint Petersburg underground environment, including sandy-clayey sediments, groundwater, gases of different genesis, microorganisms, as well as above-ground and underground structures, are analysed. Peculiar natural and technogenic processes, which activation or development can cause intensive underground space contamination, are described. The principle block diagram showing multicomponent underground space and assessing its interaction with buildings is proposed as a basis for developing computational models to ensure the long-term stability of the system.
