水平力作用下嵌岩桩桩顶内力分布的模型试验

The Model Test of the Pile Top Load Distribution Within the Rock-socketed Pile Group Subjected to the Lateral Loading

基于水平荷载下的8组模型试验桩的电测资料；分析了嵌岩桩基的实测桩顶内力的变化及分布规律，指出水平力作用下的桩顶内力分布与承台上外竖向力（和弯矩）荷载的局部分布方式有关。

Based on the electrical test data of the laterally loaded rock-socketed pile group model, the measured pile top load distributions are analyzed in this paper. And the measured pile top load is proved to be related with the distribution of the axial loading and moment on the cap.
