Abstract

There are about 1 million earthquakes of varying intensity every year in the world. Further more increase in the technogenic objects number and the necessity to create environmentally safety conditions for their operation leads to improved scientific substantiation of seismic hazard parameters of technogenic objects that could adversely effect on the environment. Therefore, the research of seismic loads on the important technogenic objects still remains the urgent issue both globally and regionally. The aim of the paper is to prevent emergencies and negative impact on the environment in case of damage, destruction and leakage of storage tanks for toxic and flammable liquids due to seismic loads of different strength. There have been treated the peak amplitudes of seismic acceleration simulation during an earthquake from 1 to 9 points at the distance to the epicenter from 10 to 1000 m, the dominant excitation frequencies at the earthquake from 1 to 9 points at the distance to the epicenter from 10 to 1000 m, the earthquake average duration with the magnitude of 1 to 9 points at the distance to the epicenter from 10 to 1000 m and  the issue of fluid oscillations in the arbitrary shell of rotation has been solved.

The results of the research will allow to select the storage tanks parameters from the influence of resonant frequencies, to prevent their destruction and to extend the service life, to minimize the ecologically hazardous impact on the environment and prevent emergencies. For the increasing the ecological safety level of the adjacent to the storage tanks territories, it has been proposed to control the effects of natural and technogenic factors on the storage tanks taking into account the forecast models of seismic changes and fluctuations in storage tanks using the algorithm for monitoring seismic loads on storage tanks.
