【摘要】：受到地形和地质条件的影响，山区高速公路桥-隧过渡段的交通事故明显较多，对人们的生命和财产安全造成严重的损害，对山区高速公路的运营安全提出了新的挑战。由于针对山区高速公路桥-隧过渡段的运营安全问题，国内外并没有规律性的理解和认识，因此，深入分析山区高速公路桥-隧过渡段运营安全的影响因素，，尽可能的防止交通事故的发生，对于提高山区高速公路桥-隧过渡段的运营安全具有重要意义。本文是以《山区高速公路特殊结构物连接段安全可靠性研究》课题为依托，以山区高速公路桥-隧过渡段为研究对象，以运营安全评价理论为指导，对山区高速公路桥-隧过渡段安全评价指标体系进行研究。论文从山区高速公路桥-隧过渡段运营安全现状出发，重点分析了人、车、路、环境对山区高速公路桥-隧过渡段运营安全的影响。其中“人”包括驾驶员交通特性和道路管理者行为，“车”是指机动车性能的安全稳定性，“路”包括道路基本设施和交通附属设施，“气候环境”是指雾、雨雪、冰冻等异常天气条件和路域环境协调性。只有在这四个要素合理配合、协调顺适，整个山区高速公路桥-隧过渡段道路运营系统才会处于安全的状态，在此基础上采取的有效措施才会使得整个运营系统安全可靠。介绍了几种常用的安全评价方法，并对比分析各自的特点和山区高速公路桥-隧过渡段本身的特点，最终选择了专家调研法进行指标筛选、G_1法进行指标的赋权，从而对桥-隧过渡段的运营安全进行综合评价。根据指标体系建立原则，建立较为全面的山区高速公路桥-隧过渡段运营安全评价指标体系框架，该框架分为三个层次，包含5个二级指标和28个三级指标。并用G_1法对专家咨询表的数据进行处理，确定各指标的权重系数。并建立评分标准，为验证指标体系和评分标准的可操作性，选择两个山区高速公路桥-隧过渡段进行了实例验证并对评价结果进行分析。
[Abstract]:Due to the influence of terrain and geological conditions, there are many traffic accidents in the transition section of highway bridge and tunnel in mountain area, which cause serious damage to people's life and property safety. A new challenge to the operation safety of mountain expressway is put forward. There is no regular understanding and understanding at home and abroad for the operational safety of the bridge-tunnel transition section of the mountain highway. It is of great significance to analyze the factors influencing the operation safety of the bridge-tunnel transition section of the mountain expressway and to prevent the traffic accident as far as possible for improving the operation safety of the bridge-tunnel transition section of the mountain highway. This paper is based on "study on Safety and Reliability of Special structure connecting Section of Mountain Expressway", taking the bridge-tunnel transition section of mountain expressway as the research object, and guided by the theory of operation safety evaluation. The safety evaluation index system of bridge-tunnel transition section of mountain expressway is studied. Starting from the present situation of the operation safety of the bridge-tunnel transition section of the mountain expressway, this paper focuses on the analysis of people, cars and roads. The influence of environment on the operation safety of the bridge-tunnel transition section of highway in mountainous area, in which "human" includes driver's traffic characteristics and road manager's behavior, and "vehicle" refers to the safety and stability of motor vehicle performance. "Road" includes road infrastructure and traffic auxiliary facilities, "climate environment" refers to abnormal weather conditions such as fog, rain and snow, freezing and so on. The road operation system of the bridge-tunnel transition section of the whole mountain highway will be in a safe state, and the effective measures taken on this basis will make the whole operation system safe and reliable. This paper introduces several commonly used safety evaluation methods, and compares and analyzes their characteristics and the characteristics of the transition section of highway bridge and tunnel in mountain area. Finally, the expert investigation method is selected to screen the indexes. G1 method is used to evaluate the operation safety of the bridge-tunnel transition section and establish the principle according to the index system. Establish a more comprehensive highway bridge-tunnel transition section of operational safety evaluation index system framework, the framework is divided into three levels. It consists of 5 secondary indexes and 28 third-level indexes. The data of expert consultation table are processed by GStud 1 method, the weight coefficient of each index is determined, and the scoring standard is established. In order to verify the maneuverability of the index system and the scoring standard, two mountain highway bridge-tunnel transition sections were selected for verification and the evaluation results were analyzed.
