针对盾构隧道安全通道设计参数缺少普适性确定方法的问题，首先采用理论计算与数值模拟结合的方法探究了单侧加压送风模式下疏散门风速与安全通道面积、疏散门间距和疏散门开启数量之间的关系，并建立了各参数间关系的数学模型；然后以安徽省马鞍山市湖北路过江隧道为例，利用PyroSim软件建立了全尺寸模型，并对比分析了其理论计算结果与数值模拟结果。结果表明：疏散门的分流流速随疏散门开启数量的增大而减小，随疏散门间距增大而减小，随安全通道面积增大而增大；根据由参数间关系建立的数学模型得出，在疏散门风速大于0.7 m/s的情况下，湖北路过江隧道疏散门开启数量应为11个，进一步确定该安全通道加压送风的最大适用长度为1 320 m；数值模拟验证结果表明该数学模型的准确性较高。研究结果可为盾构隧道安全通道单侧加压送风设计提供参考。
Abstract：In view of the lack of universal calculation method for the design parameters of the safety passageway of shield tunnel, firstly, the relationship between the velocity of each evacuation door and the area of the safety passageway, the distance between evacuation doors and the number of evacuation doors was explored by combining theoretical calculation with numerical simulation, and the mathematical model of the relationship between the parameters was established.Then, taking the Hubei Road river-crossing tunnel in Ma'anshan City,Anhui Province as an example, a full-scale model was established by using PyroSim software, and the theoretical calculation results were compared with the numerical simulation results.The results show that the number of evacuation doors opened is 11 when the velocity of evacuation doors in Hubei Road Crossing River Tunnel is greater than 0.7 m/s, and the maximum applicable length of pressurized air supply in this safety passageway is 1 320 m, and the accuracy of the mathematical model is verified by numerical simulation.The results can provide reference for the design of unilateral pressurized air supply in shield tunnel safety passageway.
