摘要

刚-柔性桩复合地基中刚性桩的荷载传递规律及变形性状明显不同于自由状态下的单桩，由于复合地基中刚性桩、柔性桩、土的互相作用，桩的工作性状要复杂得多。为了比较两者的承载变形特性，在温州地区进行同根桩在不同状态下静荷载对比试验，在静荷载试验过程中同步检测桩身应力情况，结合测试数据对桩沉降特性、荷载传递机理、压缩量特性进行了分析，分析结果对工程设计施工有一定的借鉴价值。

Abstract

The load transfer mechanism and deformation characteristics of cast-in-place piles in composite foundation with rigid-flexible piles are different from that in free state. Working property of pile is complex due to interaction between rigid pile

flexible pile and soil .Static load tests of the same pile under different situation are carried out in Wenzhou. On the basis of monitoring data in the process of static load test

settlement characteristics

load transfer mechanism and compression of pile shaft are analyzed; the conclusions can benefit to engineering design and construction.
