摘　　要：从桩基规范中有关嵌岩桩竖向极限承载力的计算入手,分析其存在的问题和不合理之处。同时,根据桩与岩石接触方式和作用力呈顺序传递的性质,进一步证明了其不合理性,以及需要改进的地方。Through analyzing the calculation of vertical bearing capacity of rock-socketed pile given in technical code for building pile foundations, some unreasonable issues in the code were found. At the same time, based on the contacting ways between the pile and the rock and the behaviors of force transfer acted step by step, the unreasonable issues have been proved and the issues to be improved were pointed out in this paper.

关 键 词：嵌岩桩 竖向承载力 规范 设计
