采用强度折减法，用Madias/GTS数值模拟软件对边坡稳定性进行分析。采用正交试验方案，取内摩擦角、内聚力与土体重度3个因素以及3个相应水平进一步极差分析，最后应用单因素敏感性分析，将其3因素敏感性大小求出，进行分析红黏土边坡稳定性影响因素的主次，为贵州红黏土边坡防护提出符合工程实际的建议。
採用彊度摺減法，用Madias/GTS數值模擬軟件對邊坡穩定性進行分析。採用正交試驗方案，取內摩抆角、內聚力與土體重度3箇因素以及3箇相應水平進一步極差分析，最後應用單因素敏感性分析，將其3因素敏感性大小求齣，進行分析紅黏土邊坡穩定性影響因素的主次，為貴州紅黏土邊坡防護提齣符閤工程實際的建議。

for the particularity of red clay slope soil in Guizhou, have a little difference with other ordinary soil slope failure mechanism, we use the strength subtraction, it use Madias/GTS numerical simulation software to analyze slope stability, by orthogonal testing scheme, Angle of internal friction and cohesion and soil heavy three factors and three levels corresponding to further analysis, the final application of the single factor sensitivity analysis, sensitivity size calculated for the three factors, carries on the analysis of red clay slope stability influence factors of primary and secondary, is Guizhou red clay slope protection conform to engineering practical Suggestions are put forward.
