摘要： 针对地下综合管廊施工发生火灾事故造成施工人员伤亡的问题，以西安市某地下综合管廊为例，开展了相关的火灾风险和人员疏散的数值模拟研究。设定不同火源位置模拟火灾发生过程，研究综合管廊温度、烟气浓度及能见度等火灾参数的变化情况。将危险参数最先达到临界值的时间作为施工人员可用疏散时间TASET；模拟相同场景下的人员的疏散情况，得到人员必要疏散时间TRSET。通过两个时间的对比，判定不同火源位置下的人员能否进行安全疏散。在此基础上，提出了两种提高疏散逃生率的优化方案。

Abstract: In order to solve the problem of casualties caused by fire accidents in the construction process of underground comprehensive pipe gallery,taking the construction site of an underground comprehensive pipe corridor in Xi'an as an example, numerical simulation study on related fire scenarios and personnel evacuation was carried out. The change of parameters such as temperature, flue gas concentration and visibility at each measuring point in the integrated pipe corridor was studied by setting different fire source position to simulate the fire process. The time that each parameter reaches the critical value first is taken as the available evacuation time TASET.The evacuation situation in the same scene was simulated to get the necessary evacuation time TRSET. Whether the personnel in different fire sources can be evacuated safely was determined through the comparison of two evacuation times. Two kinds of optimization evacuation plan were proposed to improve the evacuation rate on the basis of the research.
