Abstract

Considering the influence factors of slope stability and selecting multi-indexes to build a set-pair system of evaluation indexes and classification standards，the unified，different and opposite connection degrees of each index and standard level were built in evaluation system to determine the slope safety level. According to benefit type index and cost type index，the multiple set pair connection degrees consisted of multi-index and evaluation standards in different forms were further calculated based on the set pair analysis theory. The entropy and weight of each index were determined based on entropy theory，the comprehensive connection degree evaluation model of slope entropy weight-set pair were established by coupling entropy weight to the set pair connection degree. Analyzed the multi-index and multivariate connection degree deeply and adopted the confidence criterion to assess the stability comprehensively. The evaluation results meet engineering requirements and show that，the second phase of slope stability status is in accordance with the actual，the third phase of slope stability after excavated will be stable basically which is a little better than before excavated，so that it is beneficial to make a forecast about slope stability and avoiding danger in the third phase of excavation engineering. The proposed evaluation system of entropy weight-set pair can give a comprehensive evaluation of the slope and excavation stability objectively and deeply.
