振冲碎石桩在软土地基加固中的应用

Application of Vibration Detritus Pile In the Consolidation of Soft Foundation

以杭州秋涛路与钱塘江之间的一个住宅小区中的七层点式住宅为例 ,阐述了振冲碎石桩与饱合粉土地基形成复合地基后的共同工作状态及桩土应力比和面积置换率这二个参数的取值方法 。

Taking a 7-storey apartment located between Qiutao Road and Qiantang River as example,this paper expounded the working status of the compound foundation formed by vibration detritus pile and the saturated silt foundation,and introduced the methods to determine the parameters as the pile-sdil stress ratio and the area replacement ratio.It is proved that it's feasible to use vibration detritus pile to consolidate the saturated silt foundation.
