摘要
为研究水下公路隧道火灾工况下人员安全疏散模式,以江阴靖江过江盾构隧道为工程依托,采用Pathfinder数值模拟方法,建立人员疏散路径选择理论模型,研究“楼梯”和“滑梯”2种疏散模式下间距对人员疏散的影响,并对安全范围进行分析。研究结果表明:(1)江阴靖江盾构隧道楼梯疏散模式的最佳间距为80 m,滑梯疏散模式的最佳间距为60 m;(2)在设置坡度为45°时,滑梯疏散效果优于楼梯,当间距为60~70 m时,推荐使用滑梯进行疏散。研究成果可指导依托工程靖江过江盾构隧道防灾救援人员安全疏散设计,也可为同类隧道工程人员安全疏散提供借鉴。
In order to study the safety evacuation mode of personnel under the fire condition in underwater highway tunnel,based on the Jingjiang river-crossing shield tunnel in Jiangyin City,the Pathfinder numerical simulation method is used to establish a theoretical model of personnel evacuation path selection.The influence of the spacings of“stairs”and“slides”on personnel evacuation under various evacuation modes are analyzed,and the safety range is analyzed.The research results show that:1)The optimal spacing of the stair evacuation mode of Jiangyin Jingjiang shield tunnel is 80 meters,and the optimal spacing of the slide evacuation mode is 60 meters;2)If the slope is set to 45°,the evacuation effect of the slide will be better than that of the stairs.If the spacing is 60~70 m,it is recommended to use slides for evacuation.The research results can guide the safe evacuation design of disaster prevention and rescue personnel for the Jingjiang river-crossing shield tunnel,and can also provide reference for the safe evacuation of similar tunnel projects.
