摘要
该文通过素砼桩复合地基现场载荷试验测定桩顶反力、桩间土反力 ,研究桩、土受力特征。分析了复合地基桩土应力比 ,桩、土荷载分担比 ,桩体应力集中系数及桩间土应力减小系数的变化规律。
The determination of the pile top reaction and the inter-pile soil reaction are performed using the field plate load test in a plain concrete pile composite ground to study the force bearing characteristics of pile and soil.From these data, the paper analyzes the variation regularities of the pile-soil stress ratio,the load sharing ratio of pile and soil,the stress concentration coefficient and the stress reduction coefficient of pile body and inter-pile soil.
