| 摘 要： | 为了评估施工期高速公路隧道衬砌结构技术状况,文章运用层次分析法建立由目标层、因素层和指标层构成的递阶层次结构模型,分析影响隧道衬砌结构的各种不确定性因素；采用物元理论、模糊集合论和信息熵理论,构建熵权模糊物元评估模型.工程实例应用结果表明,交工前隧道结构技术状况为IA,衬砌破损程度等级为一般；衬砌裂缝和衬砌背后空洞是影响评估结果的最主要因素.研究认为:该评估方法考虑了指标因子的不确定性,将主观权重与客观权重相结合,避免了传统评判方法中的主观随意性,所得结果更加符合客观实际. |

| Abstract: | In order to evaluate the technical condition of an expressway tunnel lining structure,a recursion order hierarchical structure model-which consisted of a target level,factor level and index level-was proposed.Many uncertainties affecting the tunnel lining structure were analyzed and an entropy-weight fuzzy matter-element model was put forward based on matter-element theory,fuzzy sets and information entropy theory.Application to one expressway tunnel shows that before the tunnel was handed over the technica... |
