软土地区深基坑中SMW工法桩+斜撑组合支护施工技术研究

Research on Construction Technology of SMW Pile+Inclined Brace Combined Support in Deep Foundation Pit in Soft Soil Area

文中以某高层建筑为例,对排桩+锚索支护、SMW工法桩+斜支撑两种方案进行比较分析,深入研究SMW工法桩+斜撑组合支护技术在软土地区深基坑中的应用,进一步提高SMW工法桩+斜撑组合支护施工质量及安全性,减少事故发生,以期为未来软土地区类似的基坑工程提供相关实践经验。

Taking a high-rise building in Fuzhou City as an example,twos chemes of pile row+anchor cable support and SMW construction pile+inclined support are compared and analyzed.The application of SMW pile+inclined brace combined support technology in deep foundation pit in soft soil area is studied deeply.Further improve the construction quality and safety of SMW construction pile+inclined support combination,reduce the occurrence of accidents,in order to provide relevant practical experience for similar foundaiton pit projects in soft soil areas in the future.
