多因素作用下边坡稳定影响因素敏感性分析

Sensibility Analysis of Slope Stability under Multifactor Condition

影响边坡稳定性的因素很多,通过边坡稳定性影响因素的敏感性分析,可以找出影响边坡稳定的主导因素,从而为边坡的治理和设计提供依据。利用BP神经网络来分析边坡稳定性,在此基础上运用相对作用理论(RSE)确定各影响因素间的交互作用,并将交互作用应用于边坡稳定性影响因素敏感性分析中。考虑各因素交互作用的多因素敏感性分析比只考虑单因素或各因素间无交互作用的分析方法更符合边坡系统的内在规律。

The factor influencing the through the sensitivity analysis, which network was used to analyze the slope slope stability is numerous, the leading factor can be found out offered the basis for administration and design of slope. BP neural stability, then the theory of RSE （ Relative Strength of Effect） was applied to confirm the reciprocation among every influence factor on this basis, and the reciprocation was utilized to analyze sensitivity of slope stability. The analytical method accords with the inherent law of slope system even more than the traditional ones that only considering single factor or no interaction among every factor.
