摘　　要：为了研究障碍物对人员疏散的影响,采用数值模拟的方法分析了不同障碍物布局和布置形式下的人员疏散过程。结果表明,障碍物位于出口中心线上时增加了疏散距离,降低人员疏散效率,人员密度越大,障碍物距离出口越近,疏散时间延滞越严重;障碍物位于出口边界线上时对人员疏散影响较小,障碍物与出口距离为0 m时,可以有效地提高疏散效率,减少疏散时间;障碍物纵向布置较有利于人员疏散,横向布置则较不利于人员疏散。In order to research the effects of the obstacles before the exit on pedestrian evacuation ,numerical simulation is applied to analyze the evacuation process under different setting and layout of obstacles .The results show that the obstacle occurring on the exit center line increases the evacuation distance and reduces evacuation efficiency ;the higher pedestrian density is and the shorter the distance between obstacle and exit is ,the more the evacuation time delays ;the obstacle being more close to the exit border line has little effect on the evacuation ,the evacuation efficiency can be improved and evacua-tion time can be decreased .The longitudinal setting of the obstacle is conducive to evacuation and the transverse setting is not .
