【摘要】：港珠澳海底隧道是沉管法施工的水下隧道,是国际标志性工程,其建成后将成为世界上最长的海底沉管隧道,具有沿线长、埋深大、交通流量大等特点,火灾事故发生的可能性及破坏性均较大,并且造成的损失和影响巨大。本文从通风排烟、人员疏散、交通控制和灭火救援等几方面对港珠澳海底沉管隧道发生火灾时的应急救援进行了研究,本文的主要内容为： (1)运用数值模拟的方法对港珠澳海底沉管隧道安全停车距离进行了研究,在此基础上,结合港珠澳海底沉管隧道设计火源功率和汽车火灾规模,提出了港珠澳海底沉管隧道的火灾事件分级。根据港珠澳海底沉管隧道具体情况,确立了其应急救援组织机构,并确定了各机构的职责。 (2)港珠澳海底沉管隧道采用设置侧边排烟道的集中排烟系统,这种设置方式在国内尚属首次。本文给出了其不同区段具体的通风排烟方案,并给出了排烟量、诱导风速和排烟阀开启数量等具体参数。 (3)运用数值模拟的手段,得出了不同情况下隧道发生火灾时人员的可用安全疏散时间与必需安全疏散时间,通过对比分析,给出了港珠澳海底沉管隧道合理的安全门间距。通过建立流体力学方程,对沉管隧道安全门断面风速和送风量进行了求解。 (4)对沉管隧道火灾时的隧道内交通控制方案、灭火救灾方案与医疗救护方案进行了研究。在各专项应急方案的基础上给出了沉管隧道火灾事件整体响应程序和灾后恢复程序。 本文的研究成果可对港珠澳海底沉管隧道发生火灾时的应急救援工作提供技术支撑,并为类似的沉管隧道发生火灾时的应急救援提供参考。
[Abstract]:The Hong Kong-Zhuhai-Macao subsea tunnel is an underwater tunnel constructed by the sinking pipe method, and is an international landmark project. It will become the longest submarine submerged tunnel in the world after its completion. It has the characteristics of long line, large buried depth, large traffic flow, etc. The possibility and damage of fire accident are great, and the loss and influence are enormous. In this paper, the emergency rescue of underwater immersed tunnel in Hong Kong, Zhuhai and Macao is studied from the aspects of ventilation and smoke exhaust, evacuation, traffic control and fire fighting and rescue. The main contents of this paper are as follows: (1) the safe stopping distance of underwater immersed tunnel in Hong Kong, Zhuhai-Macao and Macao is studied by numerical simulation method. On this basis, the power of fire source and the scale of vehicle fire are combined with the design of submarine immersed tunnel in Hong Kong, Zhuhai-Macao. The fire event classification of underwater immersed tunnel in Hong Kong, Zhuhaiao and Macao is put forward. According to the specific situation of Hong Kong, Zhuhai-Macao submarine sinking tunnel, the emergency rescue organization is established, and the responsibilities of each organization are determined. (2) Hong Kong Zhuhai-Macao submarine sinking tunnel adopts a centralized smoke discharge system with side discharge flue. This setup is the first time in China. In this paper, the specific ventilation and smoke exhaust schemes in different sections are given, and the specific parameters such as smoke discharge amount, induced wind speed and the number of exhaust valve opening are given. (3) numerical simulation is used. The available safety evacuation time and necessary safety evacuation time of tunnel fire are obtained. Through comparison and analysis, the reasonable safety door spacing of underwater immersed tunnel in Hong Kong, Zhuhai and Macao is given. By establishing the hydrodynamic equation, the wind speed and air supply rate of the safety door section of the immersed tunnel are solved. (4) the traffic control scheme, the fire fighting and rescue scheme and the medical rescue scheme of the tunnel fire are studied. On the basis of each special emergency plan, the whole response procedure and disaster recovery procedure of immersed tunnel fire event are given. The research results in this paper can provide technical support for the emergency rescue work of underwater immersed tunnel fire in Hong Kong, Zhuhai-Macao, and provide reference for the emergency rescue of similar submerged tunnel fire.
