摘要
为分析筏板基础与压力容器的静力作用,通过建立非线性有限元软件ABAQUS建立的混凝土筏板基础与钢制压力容器的有限元模型。分析在重力荷载作用下筏板与压力容器的应力与位移场的分布规律。分析结果表明,在自重作用下板底部最大竖向位移分布在圆柱筒体与筏板基础的接触区域,钢制压力容器与C30标号的混凝土筏板基础均未发生塑性应变。
In order to analyze the static action of raft foundation and pressure vessel,the finite element model of concrete raft foundation and steel pressure vessel is established by the nonlinear finite element software ABAQUS.The distribution law of stress and displacement field of raft and pressure vessel under gravity load is analyzed.The results show that the maximum vertical displacement of the bottom of the slab under the action of self weight is distributed in the contact area between the cylinder and the raft foundation,and there is no plastic strain between the steel pressure vessel and the C30 concrete raft foundation.
