TAKING INTO ACCOUNT THE SOIL INFLUENCE AS THE ELASTIC WINKLER FOUNDATION DURING THE CYLINDRICAL TANK OSCILLATIONS UNDER SEISMIC LOADS

Abstract

Petroleum products storage tanks, which are widely used in the urban economy and industry, are ecologically dangerous sources of technogenic influence on the environment, acting as objects of uncontrolled emissions of vapor-air or vapor-gas-air mixtures and spills of petroleum products with subsequent fires and explosions. Properly designed oil storage facilities could prevent leakage and potential contamination of soil, surface or groundwater. The destruction of reservoirs is possible as a result of the sudden action of seismic loads of various strengths. The liquid stored in the tanks begins to sence intense sloshing. The phenomenon of sloshing in partially filled tanks could lead to high pressure on the tank walls, collapse of its structure or loss of stability and could cause leakage of hazardous liquid.
