摘要
为优化地铁车站设计,以某无覆土地铁车站为例,针对围护和主体结构设计中的重难点进行了分析和探讨,提出合理选用支撑形式、异形基坑分坑施工、简化支撑布置同时局部加强、利用转换结构及考虑“永临结合”等措施,有效解决了实际工程问题,可为今后类似工程提供参考。
To optimize the design of subway station,taking a subway station without soil cover as the case,the key points in the design of foundation pit support and main structure are analyzed and discussed.The measures,such as,reasonable selection of support form,division construction of special-shaped foundation pit,support layout simplification combined with local reinforcement,use of conversion structure,and combination of permanent and temporary supports,are put forward,which could effectively solve the practical engineering problems and provide reference for similar projects in the future.
