莲阳桥闸重建工程拦河闸基础处理方案优化设计

The optimition design of the foundation treament of the Lianyangqiao sluice reconstruction

莲阳桥闸重建工程拦河闸基础为浅层中粗砂,底下深厚淤泥、淤泥质软弱土层,为保障拦河闸的抗液化及抗震陷稳定、均匀沉降及控制总沉降量,其基础处理方案采用了水泥搅拌桩。本文对在深厚软弱土层地基上拦河闸基础处理的水泥搅拌桩方案设计及优化进行了介绍,供类似工程参考。

The foundation of Lianyangqiao sluice reconstruction is composed of the shallow sand,deep silt,silty soft soil,in order to protect the barrage of anti-liquefaction and seismic settlement stability,uniform settlement,and control the total settlement,the foundation treatment programs employs the cement mixing piles.This paper introdues the design and optimization of cement mixing piles applied in the sluice foundation treatment in the deep soft soil foundation.
