本文简介：
深中通道是一个24公里的桥隧系统，包括一个6.8公里的超大截面海底隧道。该隧道采用顶部水平排烟横道与侧壁排烟孔相结合的新型排烟系统，用以解决超大断面海底隧道的排烟问题。为了评估该类型隧道潜在的火灾危险，建立了1:30的隧道模型，并进行了140次海底隧道火灾小规模实验。通过改变火源功率、火源位置和风机运行方式，模拟海底沉管隧道火灾的不同场景，并对火灾烟气扩散行为和烟气温度分布等相关关键参数进行研究，针对不同的火灾场景提出最优的烟气控制策略。研究结果表明，新型排烟系统能够充分利用烟流特性，显著提高排烟效率，显著增加可用疏散时间，进一步提高超大断面海底隧道的消防安全性。
Brief Introduction：
The Shenzhen–Zhongshan Bridge is a 24‐km‐long bridge and tunnel system, including a 6.8‐km‐long super cross section subsea tunnel. To solve the smoke exhaust problem of a super large cross‐section subsea tunnel, the tunnel has a new smoke exhaust system that combines a horizontal smoke exhaust cross section at the top and sidewall smoke exhaust holes. In order to evaluate the potential fire hazards of this type of tunnel, a 1:30 tunnel model was established and 140 small‐ scale experiments on underwater tunnel fires were conducted. By changing the fire power, fire location, and fan operation mode, different scenarios of submarine immersed tunnel fire were simulated and the related key parameters such as fire smoke diffusion behavior and smoke temperature distribution were studied. On this basis, the optimal smoke control strategy was proposed for different fire scenarios. The research results indicate that the new smoke exhaust system can fully utilize the smoke flow characteristics, significantly improve smoke exhaust efficiency, and increase available evacuation time, thus further enhancing the fire safety of super large cross‐section subsea tunnels.

本文亮点：
建立30:1水下沉管隧道模型，进行140组火灾模型实验，模拟隧道火灾的各种场景。
研究了烟气的扩散规律。自然通风条件下，烟气被排烟截面有效阻隔，控制在2-3个防烟间隔内。
本工作的目的是研究排烟效果，比较不同通风量和风机运行方式的排烟效果，总结出最佳排烟方案。
Highlights：
A 30:1 underwater immersed tunnel model was built and 140 sets of fire model experiments were conducted to reproduce various scenarios of tunnel fires.
The diffusion law of smoke was studied. Without ventilation, smoke is effectively blocked by the smoke exhaust cross section and controlled within 2–3 smoke prevention intervals.
The aims of this work are to study the smoke exhaust effect, compare the smoke exhaust effects of different ventilation air volumes and fan operation modes, and summarize the best smoke exhaust plan.
