【摘要】：在高速公路隧道运营过程中,由于隧道本身的结构特点所导致的突发灾害一旦发生,就很难组织应急救援,从而造成更为严重的生命安全和财产安全的损失。从根本上来说,最好的解决方案是在突发灾害事件发生之前进行预防或者在灾害还没有进一步恶化之前进行控制。基于这一思想,本文在对高速公路隧道突发灾害风险评估的基础上,研究了高速公路隧道突发灾害的防控方法,并选取山东省济青高速为背景,设计了一个在线仿真平台,旨在从根源上减少突发灾害的发生和造成的影响。本文主要完成了以下几个方面的内容:1、以交通事故作为突发灾害事件的代表,从结构、交通流特性和事故分布特性三个方面分析了高速公路隧道交通事故的特征。2、在事故分析的基础上,研究高速公路隧道突发灾害的主动预防控制方法,主要对高速公路隧道突发灾害风险评估及防控方法展开研究,分析了风险因素,建立了风险评估模型,并通过实例进行了验证。从交通事故和自然灾害两个方面研究了突发灾害事件的防控方法。3、以山东省济青高速为背景设计了一个高速公路在线仿真与评估平台。在对先用交通仿真软件进行对比分析之后,选取Trans Modeler用于仿真模拟高速公路的运行状态。由于高速公路作为一个完整的交通系统,从平台设计完整角度,除了设计了隧道突发事件的防控与应急救援模块外,还对整体高速公路交通流运行状态模块、施工环境下和突发灾害下的高速公路运行组织保障与应急指挥调度模块进行了设计。
[Abstract]:In the process of highway tunnel operation, once the sudden disaster caused by the structural characteristics of the tunnel itself occurs, it is very difficult to organize emergency rescue, resulting in more serious loss of life and property safety. The best solution is to prevent or control a sudden disaster before it occurs. Based on this idea, this paper is based on the assessment of the sudden disaster risk of highway tunnel. The prevention and control method of the sudden disaster of highway tunnel is studied, and an online simulation platform is designed based on the background of Shandong Province Jiqing Expressway. The purpose of this paper is to reduce the occurrence and impact of sudden disasters from the root causes. This paper mainly completes the following aspects: 1, taking traffic accidents as representatives of sudden disasters, from the structure, The characteristics of traffic accident in expressway tunnel are analyzed from three aspects: traffic flow characteristics and accident distribution characteristics. On the basis of accident analysis, the active prevention and control method of sudden disaster in expressway tunnel is studied. This paper mainly studies the methods of risk assessment and prevention and control of sudden disasters in highway tunnels, analyzes the risk factors, and establishes a risk assessment model. The method of prevention and control of sudden disasters is studied from two aspects of traffic accident and natural disaster, and an online simulation and evaluation platform of expressway is designed based on Shandong Jiqing Expressway. After comparing and analyzing the traffic simulation software, Trans Modeler is selected to simulate the running state of freeway. As a complete traffic system, from the angle of platform design, in addition to the design of tunnel emergency prevention and emergency rescue module, The operation state module of the whole expressway traffic flow, the expressway operation organization guarantee and emergency command and dispatch module under the construction environment and the sudden disaster are also designed.
