边坡稳定性影响因素敏感性的两种分析结果比较

Comparison of Two Kinds of Analytical Results on Sensibility of Influencing Factors for Slope Stability

作者在刘立鹏,于红杰发表的论文基础上,采用通径系数分析方法,对影响边坡稳定性的因数进行了敏感性分析,并将分析结果与刘立鹏,于红杰灰的灰色关联分析进行了比较,结果表明:土质边坡的稳定性受土体的物理力学因素影响大,受地形地貌因素影响小;在土体的物理力学因素中,粘聚力的影响最大;在地形地貌因素中,坡角的影响最大。

Based on the paper released by Liu Lipeng and Yu Hongjie, the author analyzed the sensibility of the influencing factors of the slope stability by the method of the path coefficient. Through comparing the results with the gray correlation analyses used by Liu and Yu, the results show： the soil slope stability is affected largely by the factors of the soil physical mechanics, while little by the factors of the topography and the morphology. The cohesion is the principal factor among the factors of soil physical mechanics, and the slope angle is the biggest influencing factor among the factors of topography and morphology.
