槽钢挡土板桩在软土深基坑支护工程中的应用

摘要

某沿海电厂为填海造地场址，主厂房基础主要位于淤泥质粘土层，在汽机深基坑的开挖中采用了槽钢挡土板桩支护技术，安全合理、经济实用。本文在工程实例的基础上对槽钢挡土板桩支护技术的使用背景、设计思路，施工控制等内容进行了探讨，对软土地基深基坑开挖支护技术具有借鉴意义。%A coastal power plant is situated in the marine reclamation land. The main machine hall foundation is mainly located in silt clay layer. Channel steel breast board pile supporting technology is adopted in the steam engine deep foundation pit excavation which is safe and economic. Based on practical examples, this article discusses the application background, design idea and construction control and other content, which is of referential significance for the soft soil foundation deep foundation pit excavation and supporting technology.
