摘　　要：针对滑坡区复杂的地质条件,根据抗剪强度技术路线,利用现场测试参数分析、实验参数统计分析和参数反演分析三种方法,综合分析滑坡体抗剪强度的物理参数。通过对实验参数的统计分析,参考反演计算出的岩土物理力学参数以及当地岩土参数经验值,综合分析提出岩土物理力学参数建议值和滑坡敏感性分析主要参数取值。从而使滑坡体抗剪强度指标中重要参数C、φ得到更可靠的值。According to the Geological conditions of the slop and the method of shear strength, the physical parameters were analysised using three methods of analysis of scene test parameter, parameter statistical analysis of experiment and back analysis of shear strength parameter. By using of the statistical analysis of experiment, the trail results about physical and mechanical parameters of slope soil and the experienced value of mechanical parameter, the advised value of physical and mechanical parameters and the main value of parameters about sensitivity analysis of the slop. Based on the three methods, the value of important parameter-C, φ about shear strength were reliable.
