钻孔灌注桩侧摩阻力试验研究及修正计算

Lateral Friction Test and Amend Calculation of Bored Grouting Pile

摘要:

确定桩侧极限摩阻力的大小，目前工程上广泛采用的是以经验方法为主，辅以检测桩试验数据分析，得到的结果往往存在误差。通过静载试验以及应力测试对桩侧摩阻力的发挥模式进行分析，并结合工程实例针对桩侧摩阻力的计算提出了相应的修正系数。

Abstract:

Currently ultimate pile-side friction is determined on the basis of experience and assisted by data analysis on the testing pile， in this case， the result obtained often has some errors. Analysis was made on playing mode of pileside friction by the static load test and the stress test， and corresponding correction factors for pile-side friction calculation were put forward based on the engineering cases.
