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。
The composite metro station with finite element numerical simulation results can provide a reference for structural design. So that the structural design is effective and reasonable. In this paper, ANSYS finite element analysis software for the composite metro station numerical simulation process, respectively, from the modeling, constraint definition and temperature body load definition of three aspects of the simulation ideas and methods. Finally, the finite element analysis of station sections between two induced joints 24 meters away from each other was carried out. The calculated results are in good agreement with the measured distribution of station cracks, which shows the rationality of the proposed method and parameter selection.
