复合式地下连续墙地铁车站标准段内部结构计算

Internal Structure Calculation of Standard Segment in Composite-diaphragm-wall Subway Station

复合式地下连续墙体系是指地铁车站地连墙与内衬墙间由防水层分隔,接触面只传递法向压力的一种结构体系。对复合式地下连续墙地铁车站标准段内部结构计算原则进行了总结,并基于工程算例,分析了标准段计算模型中地连墙刚度折减系数对结构内力计算结果的影响,并在人防工况下对荷载基本组合下结构配筋量进行验算。

Composite diaphragm wall system refers to a kind of structural system that the diaphragm wall and the inner wall of subway station are separated by waterproof layer and the contact surface only transmits normal pressure.Calculation principle of standard internal structure in composite-diaphragm-wall subway station is summarized.Based on engineering example,the influence of rigidity reduction coefficient of the diaphragm wall on the calculation result of the internal structure in the calculation model is discussed.The structural reinforcement under the basic load combination is checked under the civil air defense condition.
