嵌岩灌注桩承载力设计浅析

本文通过不同地层中嵌岩桩的特点，讨论了嵌岩灌注桩的荷载传递特点和设计应用中的问题，对嵌岩灌注桩嵌岩长径比与嵌岩桩侧摩阻力、端承力、单桩极限承载力之间的关系以及嵌岩深度等问题进行了必要的探讨。

Probe to the Design of the Bearing capacity of the Rock-socketed Cast-in-place Pile

The characters of the loading transmission in the rock -socketed cast-in -place pile,the problems related to the practice design and the function of the side friction of the soils around the pile are discussed in this paper. Moreover,based on the medium weathered diorite foundation and the medium weather mudstone foundation,the relations between the ratio of slenderness of the socketed part and the side fiction,the end bearing resistance,the ultimate bearing capacity of single pile on the rock -socketed cast-in-place pile are studied.
