【摘要】：地铁建设项目具有地理位置特殊、规模庞大、投资额多、与周边环境关系密切、施工周期长等特点，从而决定了地铁工程的不确定因素多、安全可靠性低、可能引发的事故种类繁多。一旦发生地铁安全事故，其后果往往是群死群伤并造成恶劣的社会舆论影响。随着青岛地铁工程建设的全面展开，强化地铁安全风险因素的识别与分析，提高风险控制水平，显得极为重要。本文基于风险管理理论体系，，详细研究了青岛地铁区间隧道施工过程风险评估与控制的各部分内容，主要包括以下几个方面：首先，综述国内外地铁风险管理研究现状，提出本文的主要研究内容以及相应的技术路线；其次，详述风险管理理论体系，对风险识别、风险评估、风险应对等风险管理基本流程进行分析研究，为青岛地铁风险研究提供理论支持；再次，结合青岛地铁M3号线双山站~保儿站区间隧道施工特点，提出采用工作分解结构法与工程风险分解法相结合的风险识别方法，对地铁区间隧道施工主要风险因素进行识别汇总；然后，运用层次分析法与模糊数学理论，结合专家经验，对地铁区间隧道施工风险因素进行量化处理，并建立模糊综合评价体系；最后，建立风险评价矩阵R=P×C，根据风险概率模糊隶属度，综合评定地铁区间隧道风险因素的风险等级及其风险分布状态，并提出相应的风险应对措施。
[Abstract]:The subway construction project has the characteristics of special geographical location, large scale, large investment, close relationship with the surrounding environment, long construction period, and so on, which determines that there are many uncertain factors and low safety and reliability of the subway project. There are a wide variety of possible accidents. In the event of subway safety accidents, the consequences are often mass death and injury, resulting in bad public opinion. With the construction of Qingdao metro project in an all-round way, it is very important to strengthen the identification and analysis of subway safety risk factors and improve the level of risk control. Based on the risk management theory system, this paper studies the risk assessment and control of Qingdao metro tunnel construction process in detail, including the following aspects: first, summarizes the current situation of subway risk management research at home and abroad. The main contents of this paper and the corresponding technical routes are put forward. Secondly, the theoretical system of risk management is described, and the basic risk management processes, such as risk identification, risk assessment and risk response, are analyzed and studied. Thirdly, considering the characteristics of tunnel construction between Shuangshan Station and Baoer Station of Qingdao Metro Line M3, a risk identification method combining work decomposition structure method and engineering risk decomposition method is put forward. The main risk factors of subway tunnel construction are identified and summarized, and then the risk factors of subway interval tunnel construction are quantitatively treated by using AHP and fuzzy mathematics theory, combined with expert experience. Finally, the risk evaluation matrix RKP 脳 C is set up. According to the fuzzy membership degree of risk probability, the risk grade and risk distribution of tunnel risk factors are comprehensively evaluated, and the corresponding risk countermeasures are put forward.
