【摘要】：随着公路隧道数量的不断增加,隧道运营安全问题也越来越受到人们关注。公路隧道的运营环境较为封闭,有着不同于一般公路的运营特点,由于隧道内的救援逃生都面临着诸多困难,隧道内的事故往往会造成较大的人员伤亡和财产损失。因此,本文对单洞双向交通形式的等级公路特长隧道运营安全评价指标体系和评价方法进行了研究,旨在为等级公路特长隧道运营安全研究提供一定的理论基础,为其他类型公路隧道运营安全评价提供参考。本文的研究内容和研究成果主要包括以下几个方面：(1)利用德尔菲法获取的指标专家期望值对指标初选集进行优化,建立了评价指标优选集。(2)通过隧道运营环境特点和区段特性分析,提出隧道分段评价思想,并结合指标优选集,分别建立了等级公路特长隧道运营安全洞口段和隧道中段评价指标体系。(3)将乘积标度法和熵权法进行结合,建立了主客观相结合的综合权重求解方法,并且参考专家期望值确定了指标的主观权重。(4)根据国内现有规范和国内外专家学者的研究成果,建立了指标评价标准,使得指标状态更加易于鉴别。(5)依据确立的评价指标体系、指标权重方法,结合可拓理论,建立了等级公路特长隧道运营安全多级可拓综合评价模型,并通过实例验证了评价模型的有效性。
[Abstract]:With the increasing number of highway tunnels, people pay more and more attention to the safety of tunnel operation. The operating environment of the highway tunnel is relatively closed, which is different from the operation characteristics of the general highway. Because the rescue and escape in the tunnel are all faced with many difficulties, accidents in the tunnel often cause a large number of casualties and property losses. Therefore, this paper studies the evaluation index system and evaluation method of the operation safety of super long tunnel in the form of single hole and two-way traffic, in order to provide a certain theoretical basis for the study of operation safety of super long tunnel on grade highway. To provide reference for other types of highway tunnel operation safety evaluation. The research contents and results of this paper mainly include the following aspects: 1) using the expected value of the index experts obtained by Delphi method to optimize the index primary selection set. By analyzing the characteristics of tunnel operation environment and section characteristics, the paper puts forward the idea of tunnel segmental evaluation, and combines with the optimal selection set of indicators. The evaluation index system of safety hole section and middle section of tunnel is established, which combines the product scale method with entropy weight method, and sets up a comprehensive weight solution method combining subjective and objective. And the subjective weight of the index is determined by referring to the expected value of experts. (4) according to the existing domestic norms and the research results of experts and scholars at home and abroad, the evaluation criteria of indicators are established, which makes it easier to identify the status of indicators. Based on the index weight method and extension theory, a multi-stage extension comprehensive evaluation model for the safety of super long tunnels on highway is established, and the effectiveness of the evaluation model is verified by an example.
