浅析垫层厚度对复合地基承载力检测的影响

Analysis of the Influence of Bed Course Thickness on the Bearing Capacity Detection of Composite Foundation

为了研究垫层厚度对复合地基承载力检测的影响,结合不同复合地基工程实例,对不同垫层厚度条件下的复合地基静载荷试验结果进行了对比分析,结果表明,桩土应力比随着垫层厚度的增加而减小,复合地基承载力特征值会随着垫层厚度的增加而出现先增大后减小的变化,为相关工程的检测与设计提供了经验和参考。

In order to study the influence of bed course thickness on the bearing capacity detection of composite foundation,a comparative analysis was conducted on the static load test results of composite foundation under different bed course thickness conditions,combining different composite foundation engineering examples.The results show that the pile-soil stress ratio decreased with the increase of cushion thickness,and the characteristic value of the bearing capacity of composite foundation would first increase and then decrease with the increase of bed course thickness.This provides experience and reference for the detection and design of related engineering.
