在分析公路隧道群运营安全性综合评价特点和评价方法需求的基础上,提出基于集成云模型和物元分析理论的公路隧道群运营安全性综合评价方法,既能通过物元模型建立起评价对象与评价指标的对应关系,实现评价系统的信息反馈,又能通过云模型建立起概念数值表示与自然语言值描述之间的不确定性转换关系,从而实现语言值评价指标的不确定评估。最后,以西安—汉中高速公路隧道群区段为例进行工程实践应用分析。结果表明:该评价方法原理简单,可以对评价指标体系进行可拓变换,易于计算机编程研发公路隧道群运营安全性综合评价系统软件的工程推广应用。
Based on the analysis of the comprehensive evaluation of highway tunnel group operation safety and the demand of evaluation method, a comprehensive evaluation method of highway tunnel group operation safety based on integrated cloud model and matter element analysis theory is proposed, which not only establishes the evaluation object through the matter-element model And the evaluation index to realize the feedback of the evaluation system. At the same time, the uncertainty transformation between the conceptual numerical representation and the natural language value description can be established through the cloud model, so as to realize the indefinite evaluation of the linguistic value evaluation index. Finally, taking Xi’an - Hanzhong tunnel section as an example, the engineering practice and application analysis is carried out. The results show that this method is simple in principle, and it can extend the evaluation index system and make it easy for computer programming to popularize and popularize the software of highway tunnel group operation safety evaluation system.
