大型地下室温度应力分析及工程实践

Analysis of calculation method of thermal stress in a large basement and engineering practice

结合实际工程,对某大型地下室的温度应力计算方法进行了探讨,并利用有限元分析软件MISAS/GEN计算出在综合使用温差下结构的应力值,分析了设置不同的U型槽对温度应力释放的效果,分析结果表明,所采用的温度应力计算方法能够满足工程要求。

This paper gives a discussion on the calculation method of thermal stress in a large basement based on an actual project. With the help of FEA software MISAS/GEN, this paper illustrates thermal stress of the structure. Different model are given to compare the effect of U- shape stress release groove location. The resuhs shows the method in this paper are appropriate in engineering application.
