摘要
依托杭州紫之城市隧道,基于匝道公路隧道的结构特点及交通组织特点,阐述了匝道公路隧道的四种火灾场景及其救援模式。通过调研的方式确定了火源点处临界风速的计算方法。通过数值模拟的方法确定了合流隧道分支隧道火灾场景下,非火灾分支隧道临界风速,结果表明其值与火源和三岔口距离相关。火源靠近三岔口时,临界风速为2.8 m/s;火源远离三岔口时,临界风速为2.5 m/s。
Relying on the ZiZhi highway tunnel of Hangzhou,based on the structural characteristics and traffic organization characteristics of highway tunnel with ramp,the four kinds of fire scene and rescue mode of city tunnel with ramp are expounded.The calculation method of critical wind velocity at fire point was determined by means of investigation.Through the method of numerical simulation,the critical wind velocity of branch tunnel without fire in the fire scene of the branch tunnel of the combined tunnel is determined.The results show that the value of critical wind velocity of branch tunnel is related to the distance between fire and fork.If fire is closed to the fork,the critical wind velocity is 2.8 m/s;if the fire is away from the fork,the critical wind velocity for 2.5 m/s.
