插板桩在软土地基中的应用

Application of the Inserting Sheet Pile in Soft Soil Foundation

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 .

Concerning building structure of water conservancy project on the soft soil foundation,how to deal with the foundation is the key to the question,especially to building the retaining wall.It is difficult to deal with the foundation,the cost will be raised,and the time limit will be postponed owning to building the retaining wall.In this paper,the design and the construction technology of a new kind of sheet pile is introduced,and the reinforced concrete sheet pile wall is utilized as the retaining wall in part of the cofferdam project of 2 # grit chambeg of Guangnan reservoir near Shengli Oil Field.As the result,the problem of the insufficient capacity of the soft soil is solved,and it also reduce the engineering cost,the time limit,and the maintence work.It proves that it is a good way of dealing with the inserting sheet pile in the soft soil foundation.
