【摘要】 复合式地铁车站以有限元数值模拟结果可为结构设计提供参考依据。从而使结构设计有效合理。本文就ANSYS有限元分析软件对复合式地铁车站的数值模拟过程,分别从建模、约束定义及温度体荷载的定义三个方面阐述其模拟思路和方法。最后对相距24米的两诱导缝间的车站段进行有限元结构分析,发现计算结果与车站裂缝的实测分布基本吻合,从而说明本文所提模拟思路及参数选取的基本合理性。更多还原

【Abstract】 Based on FEA simulation,design of composite subway station is mere effective and appropriate.This paper illustrates the FEA simulation process of composite subway station,which includes modeling,constraint and tem- perature load.From the simulation of 24 meters long subway station,this paper also illustrates that FEA simulation process and parameters are correct and rational by the crack distribution on Shanghai metro line 2.更多还原
