摘　　要：大岩淌滑坡治理工程稳定性复核,通过现场大型直剪试验和现场原状样直剪试验,采用统计分析和工程经验类比的方法,选定对滑坡稳定分析最具敏感性的岩土力学参数C,φ值。试验成果的合理分类及成果整理的标准化为选用参数的基础,采用二维数组变异系数计算公式,配套统计修正系数法计算参数C,φ的标准值,其使用的统计意义清楚,实际应用效果较好。To check the stability of Dayantang landslide, the in-situ direct shear tests of both large areas and original undisturbed samples were carried out. Then, cohesion C and friction angle φ, which are the most sensitive geo-mechanicls parameters to the stability of landslide, were selected by using statistical analysis method and analogical method. Reasonable classification of testing results and standardization are the foundation of selecting parameters. This article puts forward the variation coefficient of two-dimensional array, and calculates the parameter C,φ with statistic revision method. Their statistical significances are clear, and the parameters can be used effectively in practice.
