摘要
以上海轨道交通9号线外环路站为实例,介绍了部分逆筑法施工的地铁车站深基坑围护结构形式,及其结构设计;着重介绍了基坑围护结构的计算模型设定、基坑稳定性计算,及围护结构的基础施工步骤。该站的部分逆筑法施工现已完成,结果表明设计是成功的。
Based on the engineering practice of the WaiHuan Station in Shanghai Urban Mass Transit Line 9, this paper analyses the structure form of the deep foundation pit and the key-nodes design by using the top-down invert method, so as to optimize the engineering. The result shows that this design is successful.
