地下车站复合墙结构内力计算分析

Composite Wall Structure Internal Force Calculation and Analysis of Underground Station

对复合墙结构地下车站进行了受力分析。建立了链杆计算模型,对重力、浮力工况分别建模计算,选取了不同的土体侧压力系数进行比较。通过有限元分析,比较计算结果得知链杆模型计算结果从理论上较符合实际情况,可以作为设计计算依据。

The stress analysis was carried out on the compound wall structure of underground station. Bar chain calculation model was established,the working condition of gravity,buoyancy modeling were separately modeling and calculation,and selected the different soil lateral pressure coefficient used in the comparison. Comparing the calculation results by finite element analysis,it was known that bar chain model were theoretically calculated results according with actual situation,which could be used as design calculation basis.
