【摘要】：城市隧道及地下工程项目建设在当前注重效率的快节奏城市生活中对于舒缓交通压力、节省地面空间、为人们提供更方便、快捷的交通方式等方面发挥了很大作用,除了在许多大城市建设使用外,现在也逐渐向中小型城市过渡,并形成了一定规模,结构建设在空间的深度、广度上都有所延伸发展。由于城市隧道工程条件的复杂性和较大的施工难度使得这些项目导致了许多人员伤亡事故的惨痛悲剧的发生,同时,伴随而来的巨大经济损失、生态环境污染和恶劣的社会影响在一定程度上也阻碍了其在人类社会今后的发展。本论文综合考虑城市隧道工程建设的复杂条件,从预防重大工程事故和降低风险发生率的角度着手,借助西北地区城市隧道工程实例,在城市隧道全寿命风险管理体系方面做了大量的研究： (1)基于复杂的工程条件和当前的理论研究现状,提出了具有普遍适用性的架构于项目建设过程、目标管理和风险管理模式上的三维RTP风险管理体系,并以两个工程实例详细说明了如何应用该体系对工程风险进行管理,从而实现进度、质量、安全、投资的管理目标。 (2)建立了把静态风险管理和动态风险管理有机结合的风险管理模式,建立了风险等级综合评估标准,并根据风险的特点和诱因把风险归为“人、机、料、法、环”五类对风险进行综合评价。 (3)把计算机运用和风险分析预测结合起来提出了计算机辅助风险动态预测技术,并把虚拟建造可视化三维动画技术和风险动态预测结合起来进行了探讨,具有一定的意义。 (4)考虑当前风险评估方法的各自的特点,选用操作性强、实用范围广的多种综合风险分析方法,搭载城市隧道全寿命风险管理体系,实现了项目总体风险和局部风险的管理,即能够对工程风险进行宏观控制又能够对风险进行查找跟踪,可以为类似工程提供一定参考。
[Abstract]:The construction of urban tunnels and underground engineering projects has played a great role in relieving traffic pressure, saving ground space and providing people with more convenient and fast transportation modes in the current fast-paced urban life, which pays attention to efficiency. In addition to the construction and use in many large cities, now also gradually transition to small and medium-sized cities, and formed a certain scale, structural construction in the depth of space, the breadth of the extension of the development. Due to the complexity of urban tunnel engineering conditions and the greater difficulty of construction, these projects have led to the tragic occurrence of many casualties, and at the same time, the accompanying huge economic losses. The ecological environment pollution and the bad social influence also hinder its future development in the human society to some extent. In this paper, considering the complex conditions of urban tunnel engineering construction, from the point of view of preventing major engineering accidents and reducing the incidence of risk, this paper makes use of the urban tunnel engineering examples in Northwest China. A great deal of research has been done on the risk management system of urban tunnel life: (1) based on the complex engineering conditions and the current theoretical research status, the universal applicability framework of the project construction process is put forward. Three dimensional RTP risk management system based on objective management and risk management mode, and two engineering examples are given to illustrate how to use this system to manage engineering risk in order to realize progress, quality and safety. (2) the risk management model combining static risk management with dynamic risk management is established, and the comprehensive evaluation criteria of risk grade are established. According to the characteristics and inducement of risk, the risk is classified as "person, machine, machine". Materials, methods, ring "five types of comprehensive evaluation of risk. (3) combining the use of computer and risk analysis and prediction, a computer-aided risk dynamic prediction technology," The combination of virtual construction visualization 3D animation technology and risk dynamic prediction is of certain significance. (4) considering the respective characteristics of current risk assessment methods, it is feasible to select. A variety of comprehensive risk analysis methods with a wide range of applications, carrying the urban tunnel life risk management system, have realized the management of the overall risk and local risk of the project. It can not only control the engineering risk macroscopically, but also trace the risk, which can provide some reference for similar projects.
