2032023年第5期詹召伟等：基于信息熵改进TOPSIS分析法的断裂构造危险性评价詹召伟等：基于信息熵改进TOPSIS分析法的断裂构造危险性评价基于信息熵改进TOPSIS分析法的断裂构造危险性评价詹召伟王彦敏高超（济宁矿业集团有限公司霄云煤矿，山东济宁272202）摘要为了准确定量化评价断裂构造发育情况，在综合分析研究区地质资料及构造纲要图的基础上，选取断层交端点密度、断层强度指数、断层密度以及断层分维值等四个参数作为定量化评价指标。依据熵权法确定各指标权重后，基于TOPSIS模型计算各指标区域得分实现了指标间的信息融合，进而借助Surfer软件绘制得分等值线图，最终依据均值—标准差分类原则划分了构造发育危险等级。结果表明：研究区存在三个危险区，通过与矿区实际情况对比发现，划分的危险分区与实际危险范围相吻合。关键词矿井突水；断层定量化指标；危险性评价；熵权法；TOPSIS分析法中图分类号TD163文献标识码Adoi:10.3969/j.issn.1005-2801.2023.05.065RiskAssessmentofFaultStructureBasedonInformationEntropyImprovedTOPSISAnalysisMethodZhanZhaoweiWangYanminGaoChao(JiningMiningIndustryGroupCo.,Ltd.,XiaoyunCoalMine,ShandongJining272202)Abstract:Inordertoaccuratelydetermineandquantitativelyevaluatethedevelopmentcomditionoffaultstructures,fourparameters,namelythedensityoffaultintersectionpoints,faultstrengthindex,faultdensity,andfaultfractaldimensionvalue,areselectedasquantitativeevaluationindicatorsbasedonacomprehensiveanalysisofgeologicaldataandstructuraloutlinemapsinthestudyarea.Afterdeterminingtheweightsofeachindicatorbasedontheentropyweightmethod,theTOPSISmodelisusedtocalculatethescoresofeachindicatorareatoachieveinformationfusionbetweenindicators.Then,theSurfersoftwareisusedtodrawthescorecontourmap,andfinally,theconstructiondevelopmentrisklevelisdividedaccordingtothemean—standarddeviationclassificationprinciple.Theresultsindicatethattherearethreedangerzonesinthestudyarea,andthroughcomparisonwiththeactualsituationoftheminingarea,itisfoundthatthedivideddangerzonesareconsistentwiththeactualdangerrange.Keywords:minewaterinrush;quantitativeindicatorsoffaults;riskassessment;entropyweightmethod;TOPSISanalysismethod收稿日期2022...
