摘　　要：为了准确评价地下陡倾采空区的稳定性,提出1种地下复杂陡倾采空区稳定性评价的改进层次分析结合逼近理想解排序(AHP-TOPSIS)法,该方法基于各影响因素之间关联性分析,选取地质因素等3个一级指标与地质构造等14个二级指标建立采空区评价指标体系,采用改进AHP法确定各指标因素权重,通过TOPSIS理论对采空区稳定性等级进行评价,并结合实例将改进AHP-TOPSIS法与其他常用方法的评价结果进行对比分析。研究结果表明:提出的改进AHP-TOPSIS法得到陡倾采空区呈现稳定状态,与现场实际工程相符,改进AHP-TOPSIS法相比于其它方法具有可靠性与优越性。研究结果可为陡倾采空区稳定性的准确评价提供参考。In order to accurately evaluate the stability of underground steeply inclined goaf,an improved analytic hierarchy process combined with technique for order preference by similarity to ideal solution(AHP-TOPSIS)method for the stability evaluation of underground complex steeply inclined goaf was proposed.Based on the correlation analysis between various influencing factors,an evaluation index system of goaf was established by selecting 3 first-level indexes(geological factor et al.)and 14 second-level indexes(geological structure et al.).The improved AHP method was used to determine the weight of each index factor.The stability grade of goaf was evaluated by the TOPSIS theory,and the evaluation results of the improved AHP-TOPSIS method were compared with other commonly used methods through case analysis.The results show that through the improved AHP-TOPSIS method,it is obtained that the steeply inclined goaf is in a stable state,which is consistent with the on-site actual project.The improved AHP-TOPSIS method is more reliable and superior compared with other methods.The research results can provide a reference for the accurate evaluation on the stability of steeply inclined goaf.
