Abstract

The uneven settlement of large oil storage tank will not only cause the tank wall to be elliptical and the upper floating plate to be blocked, but also cause the tank body to fall. In order to study the influence of uneven settlement on the tank structure, this paper takes 50000m3 oil storage tank as an example, uses the finite element simulation method to explore the influence of uneven settlement of different scales of large tank foundation on the overall stress characteristics of the tank, and obtains the storage. The influence of uneven settlement of tank foundation on the mechanics of tank body, tank bottom and large corner joint. It can provide some guidance for tank management and evaluation.
