Abstract: Horizontal buried tanks have been widely used because of their reliable performance in fireproof and antiexplosion as well as saving land resources and reducing construction cost. However, there are deficiencies in the present design and calculation methods for preventing failures of buried tanks under soil pressure. Based on rock and soil mechanics method, this paper studies the impacts of different parameters on the soil pressure acting on buried tanks. According to the results, it puts forward new calculation methods of soil pressure and soil weight load for buried tanks. The research results can provide a reference for the safety design of buried tanks.

Key words: horizontal buried tank, soil pressure, soil load, rock and soil mechanics
