地铁站台导流栏杆对人员疏散的影响研究

为研究地铁站台导流栏杆对人员疏散的影响，以某地铁车站为研究对象，采用数值模拟方法研究地铁站台导流栏杆的设置方式及长度对人员疏散的影响，为地铁车站导流栏杆的设置及优化提供参考。研究结果表明:随着固定导流栏杆长度的增加，人员疏散时间呈现增加趋势，固定导流栏杆长度为14 m时比不设导流栏杆时疏散效率降低了20.8%，人员在长度为14 m的固定导流栏杆内呈现通道型排队现象；随着可推拉导流栏杆长度的增加，人员疏散时间呈现减小趋势，可推拉导流栏杆长度为6 m时比固定导流栏杆长度为14 m时的疏散效率提高了9.7%。

Study on influence of diversion railings on personnel evacuation of subway platform

In order to study the influence of diversion railings on the personnel evacuation of subway platform, taking a subway station as the research object, the influence of setting mode and length of diversion railings on the personnel evacuation of subway platform was studied by using the numerical simulation method, so as to provide the reference for the setting and optimization of diversion railings in the subway station. The results showed that the evacuation time increased with the increase of the length of fixed diversion railings. When the length of fixed diversion railings was 14 m, the evacuation efficiency reduced by 20.8% than that of without the diversion railings, and the personnel in the fixed diversion railings with the length of 14 m presented the phenomenon of passage type queuing. With the increase of the length of push pull diversion railings, the evacuation time decreased, and the evacuation efficiency when the length of push pull diversion railings was 6 m increased by 9.7% than that when the length of fixed diversion railings was 14 m.
