摘　　要：通过对施工方案、图纸设计及材料选型进行反复论证优化,对比放坡土钉墙基坑支护形式、钢板桩+钢支撑基坑支护形式与钢板桩+钢丝绳基坑支护形式三者优缺点,得出最适合流塑性淤泥质土基础底板工程的施工工艺并形成指导方案。最终项目采用钢丝绳加钢板桩的坑中坑支护形式,该技术通过解放坑中坑中部施工空间的方式,较大提高了施工效率,总结包括在淤泥质土质背景下钢板桩免支撑支护形式的安装等具有指导性的施工技术,旨在更好地促进建筑项目工程技术的发展。Through the construction scheme,drawing design and material selection optimization,contrast slope soil nailing wall foundation pit supporting form,steel pile+steel support foundation pit support form and steel,it is concluded that the most suitable for flow plastic silt soil foundation plate engineering construction technology and form the guidance scheme.Final project using steel wire rope and steel pile pit pit support form,the technology through the liberation of the pit in the central pit construction space,greatly improve the construction efficiency,including under the background of silt soil steel pile without support form of guiding construction technology,aims to better promote the development of construction project engineering technology.
