摘要:
为研究通风对隧道内人员疏散的影响，引入通风作用力修正社会力模型，利用VS2010+Qt平台实现通风作用下隧道人员疏散速度模拟。结果表明：隧道人员疏散速度与通风风速、个体质量密切相关；通风风速增加，人员疏散速度降低且降幅逐渐增大；受个体表面积表达公式影响，个体质量对疏散速度影响以30 kg为界，当个体质量为20~30 kg时，疏散速度随个体质量增加而下降，且降幅逐渐增大；当个体质量为30~90 kg时，疏散速度随个体质量增加而上升，且上升幅度逐渐减小。研究结果为隧道通风及人员疏散方案制定提供参考依据。
Abstract:
In order to study the influence of ventilation on the personnel evacuation in the tunnel,the social force model was modified by introducing into the ventilation force,and the VS2010+Qt platform was used to simulate the personnel evacuation speed in the tunnel under the effect of ventilation.The results showed that the personnel evacuation speed in the tunnel was closely related to the ventilation wind speed and the individual mass.When the ventilation wind speed increased,the personnel evacuation speed decreased,and the decreasing amplitude increased gradually.Affected by the expression formula of individual surface area,the influence of the individual mass on the evacuation speed was bounded by 30 kg.When the individual mass was 20~30 kg,the evacuation speed decreased with the increase of individual mass,and the decreasing amplitude gradually increased.When the individual mass was 30~90 kg,the evacuation speed increased with the increase of individual mass,and the increasing amplitude gradually decreased.The research results provide a reference for the formulation of tunnel ventilation and personnel evacuation plans.
