服役公路隧道可靠性是隧道结构加固、维修的基础.为了解服役公路隧道结构可靠性,根据模糊物元分析法原理,提出基于熵权的模糊物元分析方法.把隧道结构的状态级别作为物元的事物,用衬砌裂缝、衬砌厚度、混凝土强度、衬砌背后空洞、渗漏水等评价指标及其相应的模糊量值构造复合模糊物元.通过关联度计算,得到服役公路隧道可靠性评价结果.并将分析模型应用到某公路隧道结构可靠性评价,取得了良好的效果,分析结果比传统的定性方法更为准确.为有针对性的制定合理的隧道养护对策和措施,及时进行隧道维修与加固提供科学的决策依据;也为进一步深入开展服役公路隧道可靠性研究提供借鉴和参考.
In order to understand the reliability of service tunnel structure, a fuzzy matter-element analysis method based on entropy weight is proposed according to the principle of fuzzy matter-element analysis, and the state level of tunnel structure is taken as the object Element, the composite fuzzy matter element is constructed by using the lining cracks, the thickness of the lining, the strength of the concrete, the cavity behind the lining, the seepage water, and the corresponding fuzzy values, and the reliability evaluation result of the service highway tunnel is obtained by calculating the degree of correlation The application of the analysis model to the reliability evaluation of a highway tunnel has achieved good results and the analysis results are more accurate than the traditional qualitative methods.For the purpose of formulating reasonable measures and measures for tunnel maintenance and timely maintenance of tunnels And reinforcement provide scientific basis for decision-making; also provide reference and reference for further study on the reliability of service highway tunnel.
