桩体复合地基承载力检测方法探讨

Exploration of Testing Methods for Bearing Capacity of Pile Composite Foundation

结合复合地基工程实例,对单桩复合地基载荷试验和多桩复合地基载荷试验进行了对比分析,研究了复合地基载荷试验承载力特征值与载荷板面积大小和桩体刚度的关系,得到了多桩复合地基载荷试验确定的地基承载力特征值高于单桩试验确定的地基承载力特征值的结论,为相关工程的检测与设计提供了经验和参考。

Based on the example of composite foundation engineering,a comparative analysis was conducted between single pile composite foundation load test and multi pile composite foundation load test.The relationship between the bearing capacity characteristic value of composite foundation load test and the size of load plate and pile stiffness was studied.It is concluded that the bearing capacity characteristic value determined by multi pile composite foundation load test is higher than that determined by single pile test.This provides experience and reference for the detection and design of related engineering.
