摘要

提出了用灰色关联模型对滑坡进行敏感性分析，建立了以滑坡敏感性影响因子为子序列、以其稳定性系数为母序列、以极差变化为数据转化方法、以关联度为评价结果的滑坡敏感因子分析灰色关联模型。本文以三峡库区水田坝下土地岭滑坡工程为例，选取滑带凝聚力c

内摩擦角φ

地震加速度及库水位为子序列，以剩余推力法计算的滑坡稳定性系数为母序列，得出了滑带的c

φ值对滑坡稳定性影响最为敏感的结论。

Abstract

Grey Correlation Model is employed analyze sensitivities of influencing factors. This model regards sensitive factors as sub-sequences

the corresponding safety factors as primary-sequences

top-difference as transforming method of basic data and correlative degrees as estimating indexes of sensitive factors. The model takes the Xiatudiling landslide which is located at Shuitianba

the area of the Three-Gorges reservoir as an example

and four influencing factors

respectively the cohesion of sliding zone(c)

the angle of internal friction of sliding zone(φ)

acceleration of earthquake and water level of the reservoir

are selected as sub-sequences and the safety factors

which are calculated by push method

are considered as primary-sequences. It is concluded that the values of C and φ are the most sensitive influencing factors of all of the factors.
