摘　　要：基于竖向力和弯矩荷载下７ 组模型试验的电阻片量测资料，分析了嵌岩桩基的实测桩顶内力分布规律同外荷载与桩位之间分布的关系，指出实测桩顶内力与常规ｍ 法分析的偏差同外荷载与桩位之间的分布有关．Based on the electrical test data of the rock-socketed model pile group subjected to the axial loading and the moment, the measured results of pile top load distribution related to the distribution of the load on the cap and the pile arrangement are studied in this paper. And the variation of the measured pile top load distribution with the distribution of the load on the cap and pile arrangement are also studied. The differences between the measured results and the results given by the ordinary analysis (m method) are also proved to be concerned with the distribution of the load on the cap and pile arrangement.
