摘要
在地下长通道内开展了针对一组相对位置不同的补气口—排烟口的排烟效果的全尺寸对比试验。结果表明,在地下长通道内设置的补气口—排烟口在针对发生火灾情况的优化组合上,应尽量遵循“远端补气、近端排烟”的原则。
A set of full scale contrast tests, with different relative positions of air supply opening and smoke exhaust opening, were conducted in an 88 m long underground corridor to study the effect of position of air supply opening on the efficiency of smoke extraction in a long channel. Results showed that the rule for designing the relative positions of air supply openings and smoke exhaust openings or operating them in a long channel should be “Smoke exhaust near the fire with air supply far away from the fire”.
