Abstract
In this paper, the distribution of extra stress and distortion of homogeneous soil is studied by using ANSYS
paring the result with the result by formula of criterion. Then, according to the geological
references of Cangzhou refinery in Hebei province, several methods on how to deal with foundation and
pound modulus of elasticity and Poisson’s ratio that are required in order to control the
settlement in some magnitude are concluded by using finite element analysis to simulate the extra stress
distribution of the single oil storage tank whose volume is 15×105 m3 on the basis of preceding
conclusions. The result illustrates that finite element analysis is dependable for analyzing extra stress and
distortion of the foundation of an oil storage tank. This method can provide reference for the analysis of
elasticity and plasticity of foundations and dependability for engineering design.
Introduction
Because of the new policy reformation and opening, China Petroleum & Chemical Corporation wants to set
up several oil storage tanks, considering the need for energy storage in Shanghai and Zhejiang province,
and that the volume of a single oil storage tank is up to 15×105 m3. The construction of oversized oil
storage tanks not only puts forward stricter requirement for the design of equipment and techniques, but
also increases the difficulty for the reconnaissance of geotechnical engineering and the construction of oil
storage tanks. At present, many experts in soil mechanics have made many attempts to design a foundation
for this kind of oversized oil st
