【摘要】：我国公路隧道数量与规模的逐渐扩大为公众出行带来了巨大便利,同时,隧道的特殊构造给隧道的运营管理带来了挑战,尤其是隧道发生火灾或者其他灾害性突发事件时,隧道狭长的空间限制会造成严重危险,安全形势严峻。隧道根据自身的特点配备了相应不同规模的机电系统,成为了公路隧道正常运营的重要支撑,那么机电系统的运行状态的检测与评估也成为了隧道的运营管理部门关注的重点问题。研究公路隧道机电系统运行状态评价方法,对全面了解隧道的运营状况、发现并解决隧道机电系统的安全隐患,提高隧道的运营维护水平具有非常重要的意义。本文以评价公路隧道技术状况为目标,首先广泛参考国家、行业现行的技术规范、工程设计资料,梳理并总结了公路隧道机电系统的概况;同时广泛参阅文献资料,总结了综合评价系统理论知识。在此基础上分析隧道机电系统评价需求,构建符合要求的公路隧道机电系统技术状况评价指标体系层次结构,并结合隧道机电系统基本配置特点,给出了公路隧道机电系统技术状况评价基本指标体系。其次,在考虑到隧道机电系统技术状况的实测特点,在评价指标体系结构上,探讨机电检测项目与评价指标之间的关联,从而建立了公路隧道机电设备的可靠性模型、公路隧道机电系统子系统有效度评价模型、公路隧道机电系统整体有效度评价模型。并且指出了机电系统技术状况定量评价中涉及到的关键方法—指标权重与完好率估算方法。最后以四川省华蓥山隧道机电检测为例,对所建立的公路隧道机电设备的可靠性模型、公路隧道机电系统子系统有效度评价模型、公路隧道机电系统整体有效度评价模型进行了实例计算分析。结果表明,构建的机电系统技术状况评价模型科学、合理,具备操作性,能够从整体与个体对隧道机电系统技术状况进行定量描述,反映隧道机电系统的真实运营维护状况。
[Abstract]:The gradual expansion of the number and scale of highway tunnels in China has brought great convenience for the public to travel. At the same time, the special construction of tunnels has brought challenges to the operation and management of tunnels, especially when the tunnel fires or other catastrophic emergencies occur. The tunnel narrow space restriction will cause serious danger, the security situation is grim. According to its own characteristics, tunnels are equipped with corresponding electromechanical systems of different scales, which has become an important support for the normal operation of highway tunnels. So the inspection and evaluation of the operating state of the electromechanical system has also become the key issue of the tunnel operation management department. It is of great significance to study the evaluation method of highway tunnel electromechanical system operation condition, find out and solve the hidden danger of tunnel electromechanical system, and improve the level of tunnel operation and maintenance. In order to evaluate the technical situation of highway tunnel, this paper firstly extensively refers to the current technical specifications of the country, the industry, the engineering design data, combs and summarizes the general situation of the mechanical and electrical system of the highway tunnel, and at the same time, extensively refers to the literature. The theoretical knowledge of comprehensive evaluation system is summarized. On this basis, the evaluation requirements of tunnel electromechanical system are analyzed, and the hierarchy structure of evaluation index system of highway tunnel electromechanical system is constructed, and the basic configuration characteristics of tunnel electromechanical system are combined. The basic index system for evaluating the technical condition of highway tunnel electromechanical system is presented. Secondly, considering the measured characteristics of tunnel electromechanical system technology and the structure of evaluation index system, the relationship between electromechanical inspection items and evaluation indexes is discussed, and the reliability model of highway tunnel electromechanical equipment is established. The effectiveness evaluation model of highway tunnel mechanical and electrical system subsystem and the overall efficiency evaluation model of highway tunnel electromechanical system. The paper also points out the key methods in quantitative evaluation of the technical status of electromechanical system, I. e., the index weight and the method of estimating the integrity rate. Finally, taking Huayingshan tunnel of Sichuan province as an example, the reliability model of highway tunnel electromechanical equipment and the evaluation model of the effectiveness of the subsystem of highway tunnel electromechanical system are established. The evaluation model of overall effectiveness of mechanical and electrical system of highway tunnel is calculated and analyzed by an example. The results show that the evaluation model is scientific, reasonable and operable. It can describe the technical situation of tunnel electromechanical system quantitatively from the whole and individual, and reflect the true operation and maintenance of tunnel electromechanical system.
