大型LNG全容罐在泄漏工况下的罐壁开裂分析

Analysis of Wall Cracking of Large-Scale LNG Full Containment Tan kunder Leaking Conditions

为研究LNG全容罐在泄漏工况下混凝土外罐壁的受力及混凝土开裂情况,本文采用有限元程序对某项目的160000m^3储罐进行计算分析,得到在泄漏工况下混凝土罐壁的裂缝及应力分布结果。

In order to study the stress of the concrete outer tank wall and the concrete cracking of the LNG full containment tank under the leakage condition,this paper uses the finite element program to calculate and analyze the 160,000 m3 storage tank of a project to obtain the cracks and the stress distribution results of the concrete tank wall under the leakage condition.
