摘　　要：为准确预测岩溶隧道施工引起的地表塌陷风险,运用属性评价方法建立岩溶隧道地表塌陷的风险评价体系。选取控制岩溶地表塌陷的关键因素作为溶区隧道地表塌陷风险的评价指标;构建属性测度函数用于计算各风险评价指标的属性测度;运用综合赋权法确定各评价指标的权重;最后,运用置信度准则确定地表塌陷的风险级别,并通过工程应用验证其可行性。应用结果表明:采用所建立的可拓风险评价体系得出的地表塌陷风险结果与工程实际吻合较好;体系中属性测度函数形式固定,指标权重的确定考虑了人的客观认知和事物的客观信息,这些特点可显著提高风险评价结果的可靠性。In order to accurately predict the risk of surface collapse caused by karst tunnel construction,the risk evaluation of surface collapse along karst tunnels is established by using attribute evaluation method.The key factors of controlling surface collapse along karst tunnels are selected as the evaluation index of tunnel surface collapse risk.The attribute measure functions are constructed to calculate theattribute measures of each risk evaluation index.Using the integrated weighting method to determine the weights of each evaluation index.Finally,a confidence criterion was applied to recognize the surface collapse risk level,and its feasibility is verified by engineering application.The research results indicate that the risk assessment results of ground collapse obtained by the extension risk evaluation system established in this research are in good agreement with the actual engineering practice.In the established risk assessment system,the form of attribute measure function is fixed,and the determination of index weightconsiders the objective cognition of people and objective information of things,which can significantly improve the reliability od risk assessment results.
