大型堆载条件下桩土性状的试验研究

The Test Study of Pile-Soil Behavior Under High Piling-up Weights

叙述了堆载条件下桩的受力特性和沉降特征。根据实测资料，分析了桩侧摩阻力和端承力随上部堆载的变化关系，并由此研究了大型堆载条件下的桩土性状。对堆载试验结果的可靠性进行了论证。

The paper described force and displacement behaviors under high piling-up weights. According to in-situ test data, the variation is analysed of pile skin friction and toe resistance with piling up weights. Furthermore, pile-soil behavior under high piling-up weight was studied, the result proved the feasibility of piling-up weight method.
