公路隧道群运营安全性综合评价方法

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。

Comprehensive safety evaluation method of expressway tunnel group

Through analyzing the expressway tunnel group operation safety features and evaluation theory demand,a comprehensive safety evaluation method with cloud model and matter-element analysis theory was proposed.This method can use matter-element model to establish the corresponding relations between evaluation objects and evaluation indexes for realizing the information feedback of evaluation system,and also can use cloud model to set up the uncertainty conversions between numerical value concept and natural language for realizing the uncertainty evaluation of language evaluation indexes.Finally,the method was verified by a project example of Xi’an—Hanzhong expressway tunnel group.The result show that this method can take the extension transformation into the evaluation index system,and give easy way to develop comprehensive safety evaluation system software by computer programming for engineering application.
