摘　　要：以某V形坡特长隧道为研究对象,对洞内竖井及平导横通道处所设计的避难所2种停车位置5种工况进行了疏散模拟分析,得出单洞双线隧道内不同停车位置紧急救援的必需安全疏散时间。同时结合V形坡紧急救援通风措施,对竖井区段进行了三维火灾数值模拟,比较自然通风和风速1.0 m/s纵向通风条件下火灾烟气流动和一人高处温度的分布特征,得出竖井区段的可用安全疏散时间。通过与必需安全疏散时间的比较,提出在隧道中部临近竖井处应增设一处避难所。Taking the super long railway tunnel with V-shaped slope as an example,the simulations of passengers evacuation and rescue were made for two kinds of shelter parking location which are shaft passage shelter and parallel heading passage shelter under five different conditions,and the required safe evacuation time（ RSET） for emergency evacuation and rescue of different parking location in double-track railway tunnel was concluded. Combining with the V-shaped slope emergency rescue ventilation measures,three dimensional numerical simulation of fire hazard was made for shaft section,the distribution characteristics of the fire smoke movements and temperature in one person＇s height under the natural ventilation condition and the 1. 0 m/s longitudinal ventilation condition were compared,and the available safe evacuation time（ ASET） in shaft section was determined. By comparing with the RSET,another shelter near shaft should be built in the middle of the tunnel.
