本文利用SAP5计算机程序,对北京地铁西单车站2~#施工横通道交叉点部位支护结构在工作荷载作用下,进行了空间弹性有限元分析,为结构模型试验提供理论指导。分析结果表明,2~#施工横通道交叉点部位结构设计合理,施工方法可靠。
In this paper, using the SAP5 computer program, the space elasticity finite element analysis is carried out on the support structures at the crossings of No.2 ~ # crossings of Beijing Metro Xidan Station under the action of working load to provide theoretical guidance for the structural model test. The analysis results show that the structure design of crossing points of 2 ~ # construction is reasonable and the construction method is reliable.
