地基处理是在软土地基上修建挡土墙的关键 .介绍了一种新型板桩的设计和施工工艺 ,并在胜利油田广南水库二号沉沙池围堤部分堤段工程中用钢筋混凝土板桩墙作为挡土墙 ,解决了地基承载力不足的问题 ,降低了工程造价 ,缩短了工期 ,又减少了工程维护工作量 .工程现已竣工 ,并投入使用一年多 ,运行良好 .实例证明 ,插板桩处理软土地基是一种较理想的方法 . Foundation treatment is the key to constructing retaining wall on soft soil foundation.The design and construction technology of a new type of sheet pile are introduced.With the application of reinforced concrete in the embankment section of No. 2 grit chamber of Guangnan Reservoir in Shengli Oilfield, Sheet pile wall as a retaining wall to solve the problem of insufficient bearing capacity of the foundation, reducing project cost, shorten the construction period, but also reduce the workload of engineering maintenance project has been completed and put into use for more than a year, running well. It is proved that the process of inserting sheet pile into soft soil foundation is an ideal method.
