摘　　要：以某待建城市地下道路为例,利用Pathfinder开展人员疏散研究。设置不同的人员速度、竖向疏散通道宽度、竖向疏散通道间距,分析人员疏散情况,并对人行横通道和竖向通道组合疏散方式进行研究。结果表明:疏散时间随人员速度增加而降低,降幅先快后慢;人行横通道宽2 m时,竖向疏散通道宜宽2 m;较窄竖向通道可能引起疏散时间增加;人行横通道间距大于500 m时,竖向疏散通道间距宜不大于250 m;人行横通道间距为500 m时,竖向疏散通道间距宜不大于500 m。Taking the underground road of a city to be built as an example,Pathfinder was used to carry out evacuation research.Different personnel speed,vertical evacuation channel width and vertical evacuation channel distance were set and the personnel evacuation was analyzed.The combined evacuation of horizontal and vertical passageway was analyzed too.The results showed that:the evacuation time decreases with the increase of the evacuation speed,while the rate is faster initially and then slower.When the width of the pedestrian crosswalk is 2 m,the width of the added vertical evacuation passage is recommended to be 2 m.The narrow vertical passage may cause the evacuation time to increase.When the distance betweenthe pedestrian cross walks is greater than 500m,the distance of the additional vertical evacuation passages should not be greater than 250 m.When the spacing of the pedestrian cross walks is 500 m,the spacing of the vertical evacuation passage should not be more than 500 m.
