基于非线性系统的边坡影响因素灵敏度分析

Non-liner system sensitivity analysis on influence factor of slope stability

为优化露天矿开采方式、处理紧急情况,需掌握影响边坡状态的影响因素对边坡稳定性影响的灵敏度。鉴此,在能考虑众多影响因素及施工间交互影响的岩石工程系统理论基础上,运用智能方法生成一个动态的网络结构、建立影响各边坡稳定性因素的岩石工程系统矩阵,分析形成岩石工程系统矩阵的网络结构隐含信息,得出系统中各因素对边坡稳定性影响的灵敏度,最后将此方法用于一个边坡稳定性及影响因素灵敏度分析。

In order to optimize the extraction style of open mine and deal with emergent situations, it is necessary to know the of sensitivity of element affecting of slope stability. Based on the geotechnical engineering system theory which can regard the geotechnical engineering as a whole system and consider various factors and their interactions as well as the effect of the engineering state by construction, utilizing the intelligence method and combining the samples, the paper sets up a dynamic network construction and establishes a geotechnical engineering system matrix of each slope sample, and analyzes on the network information, then the sensitivity of every influence factor is obtained. At last this method is applied to sensitivity analysis which affects the open mine slope stability.
