预制管桩-水泥搅拌桩在软土地基处理中的应用
Application of Prefabricated Pipe Piles and Cement Mixing Piles in SoftSoil Foundation Treatment
摘要
Abstract
In order to solve the stability problem of bridge foundation located on deep silt layer foundation of an irrigation area project,precast pipe piles are introduced to control foundation settlement while cement mixing piles are used for foundation treatment.The pile foundation is arranged in grid type,and the cement mixing piles are composed of a square grid,and the precast pipe piles are arranged in the middle of the grid.The treatment scheme has the advantages of cement mixing pile and rigid pipe pile at the same time,which greatly improves the bearing capacity of the foundation,effectively controls the settlement of the deep silt layer through pipe pile,and solves the problem that the settlement of the deep silt layer is difficult to control.After treatment,the bearing capacity of the composite foundation is effectively increased from 103.43kPa to 166.12kPa,and the settlement of the composite foundation is reduced from 160.46mm to 13.86mm,which can provide reference for the design and test of the composite foundation with deep silt layer in similar soft soil areas.关键词
