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

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.
