摘要
通过复合地基现场原位静载荷试验,测定板底反力,研究桩、土受力特性和后压浆素砼单桩承载力的提高幅度,分析了复合地基桩、土应力比,桩、土荷载分担比的变化规律和后压浆素砼桩复合地基的有效作用。
The determination of the subsoil reaction are performed using the field load test in a composite foundation to study the force bearing characteristics of pile and soil.This article describes the increasing scope in bearing capacity of single pile and analyzes the variation regularities of pile-soil stress ratio awd the load sharing ratio of pile and soil.
