复杂环境下软土基坑钢管桩围护体系研究

Study on Steel Pipe Pile Enclosure System for Soft Soil Foundation Pit in Complex Environment

以上海大芦线航道整治二期工程(大治河)6标段航都路桥承台工程为研究对象,立足于工程实践,从设计选型和工程施工两个层面深入研究了软土地层条件下小型基坑的钢管桩围护体系,为类似工况条件下的基坑工程提供了围护设计选项与技术借鉴。

Taking the Hangdu Road Bridge Base Slab Project in(Dazhi River) Tender Section 6 of Shanghai Dalu Line Channel Improvement Phase II Project as the study object and based on the engineering practices,the article further studies the steel pipe pile enclosure system of small-sized foundation pit in the soft soil stratum from two aspects of design selection and engineering construction, which provide the enclosure design selection an technical reference for the construction of foundation pit in the similar construction conditions.
