复合地基桩土面积置换率的理解与分析

Understanding and analysis of replacement ratio of pile foundation area in composite foundation

介绍了等效圆直径的概念与其和复合地基桩土面积置换率的关系,通过工程实例,提出了等效圆直径在计算桩土面积置换率时的局限性,总结了各种布桩情况下对复合地基桩土面积置换率相对便捷的计算方法。

This paper introduces the concept of equivalent circle diameter and its relationship with the replacement rate of pile-soil area in composite foundation, puts forward the limitation of equivalent circle diameter in calculating the replacement rate of pile-soil area through an engineering example, and summarizes the relatively convenient calculation method for the replacement rate of pile-soil area in composite foundation under various pile laying conditions.
