摘要
介绍直径为 1 0m ,长度为 68 0 3m的钻孔灌注试验桩的静载测试试验 ,对荷载 -沉降量曲线、桩身轴心压力沿深度的分布规律、桩侧摩阻力与桩土相对位移关系以及桩端反力等进行了计算分析 。
It is introduced that the static load test method of a bored cast in situ pile with 1.0m of diameter and 68.03m of length tested in the highway bridge project from Jiaozuo to Gongyi across the Yellow River. The relationship of load to subside,the distribution of centric compressed force along pile depth,the relationship of friction force around pile to relative displacement between pile and soil,and the end active force of pile are analyzed. The unit ultimate friction force of the main layer of soil and the ultimate bearing capacity of the test pile are proposed.
