在阐述正交试验设计方法的基础上,结合下土地岭滑坡工程实例,选取了6个影响因素进行敏感性分析,极差分析及方差分析结果表明:6个影响因素的敏感性由大到小依次为内摩擦角、库水位变化H、地震加速度系数a、内聚力C、滑体容重γ、路面荷载Q,而内摩擦角、库水位变化H、地震加速度系数a是下土地岭滑坡稳定性的高度显著影响因素,内聚力C是该滑坡稳定性的显著影响因素。
Based on the orthogonal test design method and six cases of Xiandaliling landslide project, sensitivity analysis was made. The range analysis and variance analysis showed that the sensitivity of the six influencing factors was from large to small Followed by the internal friction angle , the change of reservoir water level H, the earthquake acceleration coefficient a, the cohesion C, the weight of the slide body γ, the road load Q, while the internal friction angle , the change of reservoir water level H, the seismic acceleration coefficient a is the stability The highly significant influencing factors of sex and the cohesion C are the significant influencing factors of the landslide stability.
