管桩组合新型复合地基关键技术应用

Key technology application of new composite foundation of combination pipe pile

针对水利工程实践中深厚软土地基处理的问题,以沿江地区大型水闸裕溪节制闸为例,介绍了管桩长短桩、水泥搅拌桩浅层截渗墙、改良褥垫层等管桩组合新型复合地基综合处理技术,解决了深厚软土地基水工建筑物沉降及水平变形控制问题。

Aiming at the deep soft soil foundation treatment during the hydraulic engineering,taking Yuxicheck gate along Yangtze River as an example,this paper introduces the new foundation treatment technique with composite pile of long-short pile,shallow cut-off wall of cement mixing pile,modified cushion and so on,which has solved the problem of settlement and horizontal deformation of hydraulic structure of soft soil foundation.
