摘要
通过计算机模拟,分析在火灾工况下电梯竖井对烟气运动的影响。模拟结果表明利用设在站台中部的电梯竖井进行人员疏散具有很大危险性,但是在一定条件下可以利用电梯竖井进行辅助排烟。设在站台端部的电梯若与火源分别位于站台两端,则可以发挥人员疏散作用。计算结果表明地铁车站站台挡烟垂壁设置情况、电梯井平面尺寸、竖井高度、火源功率等因素均会对电梯井内烟气流动产生影响。
Numerical analysis is used to study the feasibility of using accessible elevator shaft to extract fire smoke in a subway station. The results show that the elevator suited in the center of the platform is dangerous as evacuate way,however it can distribute to fire smoke exhaust. The elevator lie in the endpoint of the platform is enough far away from fire can be chosen as exit way. The dimension of the elevator shaft,distance away from fire,fire power,the height of shaft will decide whether the elevator shaft can be smoke way or evacuate way.
