摘要
结合上海及周边地区典型软土地层条件,对常用钢管桩的支护刚度和变形特性进行分析。针对不同基坑深度和环境保护等级,分析不同形式组合钢管桩的适用性。以武宁路快速化改建工程为实例,采用新型三联式钢管桩结构形式对周边环境影响较小,并对快速施工方法进行总结。
Combined with the typical soft soil stratum conditions in Shanghai and its surrounding areas,the support stiffness and deformation characteristics of common steel pipe piles are analyzed.According to different foundation pit depths and environmental protection levels,the applicability of different forms of composite steel pipe piles is analyzed.Taking the rapid reconstruction project of Wuning Road as an example,the new triple steel pipe pile structure has little impact on the surrounding environment,and the rapid construction methods are summarized.
