The monitoring data are the results of comprehensive action of all factors,and the focus and difficult issue for the present study on high slope is to find out the implicit rule and evaluate the stable state accurately and comprehensively from above-mentioned monitoring data. Therefore, the research objects, evaluation indexes and index values were integrated together with the improved matter-element extenics theory. Based on the long-term monitoring information,the multi-level and multi-index safety evaluation model for the left bank slope of Jinping I Level Hydropower Station was established. With the comprehensive consideration of problems concerning the contradiction between the evaluation factors,the qualitative and quantitative coexistence and the unclear crossing boundaries,the gradationally progressive analysis was performed from local to whole areas. The research results show that the bulk mass is in a stable state,the safety monitoring information is fully used,and the multi-attribute and incompatible as well as the comprehensive qualitative and quantitative evaluation problems in the complex high slope are effectively solved. Furthermore,the steady state is described comprehensively and meticulously,the dynamic analysis from static state to long-term is realized,and the research can provide some references for the similar projects.
