摘　　要：为提高公路隧道围岩分级的准确性,丰富风险评级方法,首先基于可拓物元理论,对实测数据进行无量纲化处理并转化为Vague集。然后通过AHP法和熵权法得到主客观权重,进而构建区间权重并按照隶属度与非隶属度距离最大化原则进行优化。最后建立基于Vague集的可拓安全评估模型,并结合工程项目进行案例分析,结果与实际监测数据一致。In order to improve the accuracy of highway tunnel surrounding rock classification and enrich the risk rating methods,the dimensionless treatment of the measured data and transformation into the Vague sets are carried out based on the extension matter-element theory.Then the subjective and objective weights are obtained by AHP method and entropy weight method,and the interval weights are constructed and optimized according to the principle of maximizing the distance between the membership degree and the non-membership degree.At last,the extension safety assessment model based on Vague sets is established and combined with engineering projects for case analysis,and the results are consistent with the actual monitoring data.
