| Abstract: | Based on factor analysis of slope stability,the orthogonality analysis method was put forward.The factor levels were arranged by orthogonal matrix.The factors of slope stability were calculated by reasonable computational model.The factor sensitivity was evaluated by difference analysis and trend analysis.The 10 m soil slope was analyzed by the method.On this foundation,validity of the method was discussed. |
