SMW围护结构在上海地铁基坑中的应用

The application of SMW exterior-protected structure in foundation pit construction of Shanghai subway

结合上海某地铁车站的施工方法及监测数据,对该围护形式在地铁深基坑中的应用作了初步分析和总结,并提出了一种估算内插型钢弯矩的方法,可以较好的应用在工程实践中,指出该工法在地铁车站基坑施工中具有良好的应用前景。

Combined with construction method and monitoring datum of a certain subway station in Shanghai,the author analyzes and summarizes the application of SMW exterior-protected structure in deep foundation pit of the subway,proposes a method to calculate bending moment of internal inserted shaped steel, which can be well applied in practical engineering,and points out that this SMW construction method has well application prospect in foundation pit construction of subway station.
