海相淤泥土质下的水工构筑物深基坑施工技术研究

Research on Construction Technology of Deep Foundation Pit of Hydraulic Structure under Marine Silt Soil

摘要: 本文以连云港市徐圩新区第二水厂及配套管网二期工程为例，通过分析工程地质、水文情况、支护设计及施工等方面，最后基坑采用较为经济安全、节约工期的拉森钢板桩 + 钢支撑围护体系，取得了良好的支撑效果，为今后类似沿海土质的工程深基坑支护施工提供技术参考。

Abstract: This article takes the second phase of the second water plant and supporting pipeline network in Xuwei New district, Lianyungang city as an example. Through the analysis of engineering geology, hydrological conditions, support design and construction, etc.,Finally, the foundation pit adopts a relatively economical, safe, and time-saving Larsen steel sheet pile and steel support enclosure system, which has achieved a good support eff ect.It provides technical reference for the support construction of deep foundation pits similar to coastal soils in the future.
