摘　　要：为研究电梯井加压送风和电梯前室加压送风时的防烟效果,在10层高的建筑内开展了火灾实体试验。试验分别对电梯井和电梯前室进行送风,得到了两种送风方案的防烟效果,获得了两种送风方案的临界参数,对目前针对电梯井和电梯前室送风方式开展的理论研究进行了验证,为电梯井及前室加压送风方案的选择提供参考,并为电梯疏散和"安全核"等相关研究提供技术支持。The research team carried out fire experiments in a 10-storeyed building to check out the efficiency of smoke preventing with pressurization plans for elevator shaft and its atrium.In the experiments,the team pressurized the shaft and its atrium respectively to see how the smoke preventing efficiency varies and managed to obtain critical parameters for each plan;they also verified the theories coming into existence so far with regard to pressurization of shaft and its atrium.This study would be a reference for someone who is making a choice between those two pressurization plans;it also provides technical support for related studies,such as elevator evacuation and 'safe core'.
