高置换率CFG桩加固填土地基实例

On cases for filler foundation consolidated by CFG pile with high replacement rate

以工程勘察报告为依据,结合工程实践经验,从复合地基的构造形式和受力机制两方面,对高置换率条件下桩间土的受力特性进行了分析,论述了采用高置换率对削弱桩间填土的不均匀影响和充分发挥其承载力的作用,以提高地基承载力、减少地基沉降。

Based on the engineering survey report, the paper analyzes the stressed features for the soil of piles with high replacement rate from the component forms and stressed mechanism of the composite by combining with the engineering practice, and indicates the high replacement rate can weaken the uneven influence of the fillers of pile and its potential can be further developed, so as to enhance the loading capacity of foundation and reduce the settlement at foundations.
