【摘要】：突水涌泥是岩溶地区修建隧道工程所遇到的后果最严重的灾害之一,它不仅会影响施工的进展、给洞内各类工作人员造成生命威胁,若事后没有采取必要措施,还会造成隧道工程所在地域的地表和地下环境恶化,给隧道建成后的运营造成隐患。因此,研究一种科学及普适性的方法对特长岩溶隧道中的突水涌泥灾害进行风险评价,对风险进行控制和管理是十分必要的。本文以罗依溪隧道为工程依托,针对突水涌泥灾害进行了风险模糊评价以及风险控制管理研究,主要研究内容如下：(1)针对突水涌泥风险,将国内外学者在岩溶隧道工程风险评价领域所作出的研究成果进行了综述,总结了特长岩溶隧道风险模糊评价和控制管理所存在的问题主要是没有一种绝对客观的风险评价方法和一种系统有效的风险预警体系；(2)介绍了依托工程罗依溪隧道的工程地质环境等条件,按照2011年中华人民共和国交通运输部颁发的风险评估标准,对隧道进行了施工安全总体风险评估；(3)针对突水涌泥这一岩溶隧道的特殊高危风险,进行了风险因子辨识,建立了风险因子层次结构图,采用模糊综合层次分析法(FA-AHP-RA)对风险进行了评价,基于三段式动态评估方法,分析了设计、施工前和施工时三个不同阶段隧道发生突水涌泥风险的主要致险因素；(4)对突水涌泥风险的控制和管理进行了研究,提出岩溶探测技术是突水涌泥风险风险源的辨识方法,建立了针对突水涌泥风险的四级综合地质预报方案、突水涌泥风险预警系统以及风险应急预案。
[Abstract]:Water and mud inrush is one of the most serious disasters in the construction of tunnel in karst area. It will not only affect the progress of construction, but also threaten the lives of all kinds of workers in the tunnel, if necessary measures are not taken afterwards, It also causes the deterioration of the surface and underground environment in the tunnel area, which will cause hidden trouble to the tunnel operation after completion. Therefore, it is necessary to study a scientific and universal method to evaluate the risk of water inrush and mud inrush in extra-long karst tunnel, and to control and manage the risk. Based on the Luoyi River Tunnel, the risk fuzzy evaluation and risk control management are studied in this paper. The main contents are as follows: (1) aiming at the risk of water and mud outburst, This paper summarizes the research achievements made by domestic and foreign scholars in the field of risk assessment of karst tunnel engineering. The main problems in fuzzy evaluation and control management of karst tunnel risk are that there is no absolute objective risk evaluation method and a systematic and effective risk warning system. (2) based on the engineering geological environment and other conditions of Luoyi River Tunnel, the overall risk assessment of the tunnel construction safety is carried out according to the risk assessment standard issued by the Ministry of Communications and Transport of the people's Republic of China in 2011; (3) aiming at the special high risk of karst tunnel, the risk factors are identified, the hierarchical structure of risk factors is established, and the risk is evaluated by fuzzy comprehensive analytic hierarchy process (FA-AHP-RA). Based on the three-stage dynamic evaluation method, the main risk factors of the risk of water inrush and mud inrush in three different stages of tunnel are analyzed, including design, construction and construction. (4) the control and management of the risk of water and mud inrush are studied, and the karst detection technology is proposed as the identification method of the risk source of water and mud outburst, and a four-level comprehensive geological forecast scheme for the risk of water and mud inrush is established. Risk early warning system and risk contingency plan for water and mud inrush.
