以大型立式圆筒型储罐为研究对象,采用简化建模研究大型储罐的结构应力,应用有限元软件ANSYS,对罐体、地基和基础建立三维有限元模型.在结构静力的分析中,把储液等效成梯度压力,罐体与地基之间的相互作用采用了接触面的方式,得到了罐体、地基和基础的应力和位移情况.%This paper takes the large vertical storage tank as object of study. and uses finite element analysis software ANSYS to establish 3d finite element models of storage tank, foundation and base. In the static structure analysis, the liquid and the surface between the storage tank and foundation are used as pressure gradient and contact surface to obtain stress and displacement of the tank body, foundation and base.
