浅谈钢板桩在深基坑支护中的应用

摘要

以天津市南港工业区某雨水泵站出水管顶管井及进水箱涵基坑工程为例，通过对地质条件和支护方案进行分析比选，确定采用钢板桩支护方案。本文结合工程实例，讨论深基坑支护中钢板桩的实施方法，并提出了钢板桩支护结构施工便捷、节约材料的优点。%Taking outlet pipe top tube well and water culvert foundation pit engineering of a rainwater pumping station in Tianjin Nangang industrial zone as an example, the scheme of adopting sheet pile supporting was determined through the analysis on geological conditions and supporting schemes. Combining with engineering practice, this paper discussed the methods of adopting steel sheet pile in the deep foundation pit supporting, and put forward the advantages of steel sheet pile support structure, i.e. convenient construction and saving material.
