地铁车站各设计状况的结构分析

Structural Analysis for Various Design Situations of Subway Stations

讨论地铁车站结构分析时应考虑的几种设计状况。结合工程实例,针对位于高水位地区的地铁车站,提出持久设计状况的两种受力模式;采用轨道交通领域的人防设计规范进行偶然设计状况的分析,同时运用反应位移法进行地震设计状况的分析。通过比较,找出它们对地下结构使用和安全的不同影响,从而对地铁车站结构设计提供借鉴。

The paper discusses several design situations to be considered for structural analysis of subway stations. Considering an engineering example with high groundwater level, two computation models were put forward for the last design. Accidental design situation was performed in line with the code of civil air defence of rail transit. At the same time, seismic design situation was carried out by adopting a response displacement method. By comparing the results obtained, different influences on the use and safety of underground structures for various situations were clarified which will have certain significance for structural design of subway stations.
