基于一维自由场分析对洞桩法车站进行反应位移法及时程分析法抗震计算

Seismic Calculation of Tunnel Pile Station by the Method of Reaction Displacement and Time History Analysis Based on One-Dimensional Free Field Analysis

面对复杂的环境,采用洞桩法暗挖修建车站屡见不鲜,同时,由于近年来发生的大地震中地下结构发生过严重破坏,对地铁车站进行相关的抗震验算分析不可或缺。在地下结构抗震设计简化分析方法中,反应位移法与时程分析法应用广泛。论文通过一维自由场分析取得更准确的地层相关数据,并对2种计算方法进行对比分析。

In the face of the surrounding complex environment, it is not uncommon to use the hole pile method to build the station. At the same time, due to the severe earthquake in recent years, the underground structure has been seriously damaged, so it is indispensable to carry out relevant seismic checking analysis on the subway station. In the simplified analysis method of seismic design of underground structures, the response displacement method and time history analysis method are widely used. In this paper, more accurate stratum related data are obtained through one-dimensional free field analysis, and two kinds of calculation methods are compared and analyzed.
