地铁换乘车站结构内力计算分析

CALCULATION AND ANALYSIS OF THE STRUCTURE DESIGN OF SUBWAY INTERCHANGE STATION

以某地铁岛车站主结构单拱、单柱复合衬砌结构为研究对象,采用三维有限元分析方法对其进行分析计算。根据地下工程有限元分析的原则和要求,利用有限元软件MIDAS/GTS计算分析了主体结构荷载效应的最不利组合。同时,根据其主要控制截面,建立了有限元分析模型,在受力条件下进行了有限元分析,得到了相应的计算结果。

In this paper, a three-dimensional finite element analysis method is used to analyze the structure of single arch and single column composite lining of the main structure of subway island station. According to the principles and requirements of the finite element analysis of underground engineering, the most unfavorable combination results of the main structure load effect are analyzed by using the finite element software MIDAS/GTS. At the same time, the finite element analysis model is established according to the main control section, the finite element analysis is carried out under the stress condition, and the eorresoonding calculation results are obtained.
