基于可拓层次分析法的隧道病害评估方法及应用

Method and Application of Tunnel Disease Assessment Based on Extension Analytic Hierarchy Process

依据隧道病害调查及检测结果,将隧道病害进行分类,采用层次分析法将隧道病害分为三级指标,利用可拓学理论确定各因素的权重,形成权重集,利用权重集与单因素模糊评价矩阵的合成算法,最终得到隧道病害模糊评价模型,并将定量化的评价结果与现行规定中的评价等级进行对应。最后通过具体隧道工程,采用建立的隧道病害评估模型进行评价,得到的结果与专家评价一致,验证了该评价模型的准确性,可作为隧道病害评价的选择方法。

According to the disease mechanism and the detection results of the tunnel,tunnel disease is classified,tunnel disease fuzzy evaluation model based on analytic hierarchy process and extension theory. Tunnel disease is divided into three level indicators,and extension theory is used to determine the weight of each factor,forming set of weights,merging algorithm is also used for the weight set and single factor fuzzy evaluation matrix. The quantitative evaluation result of model is corresponding to the evaluation grade of present provisions. Finally,one tunnel is selected as the project example,evaluating the health condition of the selected tunnel using the model,and the result is consistent with the expert evaluation,it is verified the accuracy of the model and shown that the model can be used as a method for the evaluation of tunnel disease.
