摘  要:为了研究隧道安全通道内人员疏散的影响因素,以苏州某超长水下公路隧道为研究对象,运用Pathfinder软件对比不同安全通道内变电所布置、安全门间距、变电所侧疏散宽度工况下人员疏散时间及变电所处人员拥堵情况。根据研究结果,建议:安全通道内变电所的布置、安全门间距分别选取20 m,100 m,尽量缩短人员在安全通道内疏散过程中的拥堵时间;安全通道内变电所侧疏散宽度取2.5 m,既能满足人员在安全通道内疏散需求,又可避免人员在安全通道内长时间拥堵,影响隧道内剩余人员疏散。In order to study the influencing factors of personnel evacuation in the safe passage of tunnel,a super-long underwater highway tunnel in Suzhou was taken as the research object,and Pathfinder software was used to compare the personnel evacuation time and personnel congestion in the substation under different conditions of substation layout,safety gate spacing,side evacuation width of the substation in the safe passage.According to the research results,it is suggested that the layout of the substation in the safe passage and the distance between the safety door should be respectively 20 m and 100 m,so as to shorten the congestion time in the evacuation process in the safe passage as far as possible.The evacuation width of the substation side in the safe passage is 2.5 m,which can not only meet the evacuation needs of personnel in the safe passage,but also avoid the long-term congestion of personnel in the safe passage,which will affect the evacuation of the remaining personnel in the tunnel.
