上盖开发车辆基地高大厂房热烟试验研究

Research on Thermal Smoke Test of Tall Factory Buildings in the Upper Development Vehicle Base

为探索排烟模式、排烟量指标和火源功率对上盖开发车辆基地排烟效果影响的规律,选取广州地铁两个典型的车辆基地陇枕停车场和陈头岗停车场作为试验对象,在车辆基地的厂房内进行全尺寸热烟试验。试验结果表明点式排烟可更好地控制烟气,而增大排烟量对烟气控制效果有限。

To explore the influence of smoke exhaust mode,smoke exhaust volume index,and fire source power on the smoke exhaust effect of the overlying development vehicle base,two typical vehicle bases in Guangzhou Metro,Longzhen Parking Lot and Chentougang Parking Lot,were selected as experimental objects for full-scale hot smoke tests in the factory buildings of the vehicle base.The experimental results indicate that point exhaust can better control smoke,while increasing the exhaust volume has limited effect on smoke control.
