Finite Elements Analysis on Weak Foundation of Oil Storage Tank

In this paper, the distribution of extra stress and distortion of homogeneous soil is studied by using ANSYS and comparing 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 minimum compound 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.
