摘　　要：针对某特长城市地下道路，借助于疏散模拟软件BuildingEXODUS，设定不同疏散场景进行模拟分析，得出了各疏散场景下人员疏散到无烟隧道及地面所需的时间。模拟结果表明：9个场景疏散完毕所需的时间约为6～11min。由于无烟环境下预测的各场景所需的疏散时间相对较长，火灾环境下应采取一定的烟气控制措施，以保证内部人员的安全疏散。The egress time under different evacuation scenarios in a long urban underground traffic tunnel were predicted by the numerical methods with the software BuildingEXODUS. The e- gress time to the parallel tunnel without fire and the time to the ground surface were obtained. Numerical results showed that the egress times of 9 scenes are within 6~ 11 minutes. These times are too long comparing with the smoke spread time in a fire condition, and smoke control measures need to be taken in order to give smoke free environment for the people evacuating safely.
