摘要
通过理论分析和工程试验 ,研究了半刚性碎石桩复合地基桩土荷载分担比 ,分析了半刚性碎石桩复合地基的分界桩土应力比和荷载分界点 ,证明了随着荷载的增加 ,桩分担荷载的比例呈现增大的趋势。计算了桩间土应力折减系数 ,发现荷载超过某一数值以后 。
This paper studies the bearing ratio of pile to soil, analyses boundary stress ratio of pile to soil and boundary load point and proves that the bearing ratio of pile to soil is gradually raised with load increasing in the semi rigid pile columns composite foundation. Stress reduction coefficient of pile and nearby soil is calculated, and it is a steadily numerical value at some load.
