AN ANALYTICAL SOLUTION FOR SINGLE PILE IN NON-HOMOGENEOUS SOIL CONSIDERING SOIL HARDENING BEHAVIOR OF PILE TIP

摘要: 桩侧和桩端采用不同的荷载传递函数,并将桩侧土体沿深度变化的剪切模量和强度进行线性拟合,在此基础上提出了一种非均匀土中单桩沉降的解析算法,推导了一系列单桩沉降解析表达式,计算结果可直接用于单桩分析,同时讨论了参数的取值问题,给出了简单的参数取值方法,计算结果与实测结果基本一致,证明了此方法的可行性。Abstract: Using different load-transfer functions for pile shaft and pile tip, the lateral soil shear modulus and strength are linearly fitted along the depth, based on which a set of analytical equations for axially loaded single pile in non-homogenous soil is set up. The solution can be used to analyze the load-settlement behavior of single pile. A simple method to determine the calculation parameter is proposed. Comparison between the results obtained from the proposed method and the load test showed the effectiveness of this method.
