摘　　要：基于计算桩内力变形的综合刚度和双参数法,从变形连续的观点出发,对成层岩体中抗滑桩锚固段的内力和变形进行了理论分析,并导出了解析解,以更真实的反映桩土之间的相互作用对内力、变形的影响。Based on composite stiffness principle and method of biparameter for calculating the internai force and deformation of pile from the viewpoint of deformation continuity, the internai force and deformation of anti-slide pile anchorage length in layered rock mass are analyzed, and the analytical solution is derived. The results reflect more truly the effect of pile-soil interaction to internai force and deformation.
