摘　　要：建立避难走道试验平台及其测试系统,开展了实体火灾试验,对火灾条件下避难走道的防烟技术进行了研究.结果表明,避难走道应设置前室,且前室内应设置正压送风,前室余压应在25～30 Pa,并应设甲级防火门;避难走道内也应保持余压在25～30 Pa.The refuge walkway experimental platform and test system was built,and full-scale fire experiment was carried out,to research the smoke control technology of the refuge walkway.Results showed that a refuge walkway should have a anterior with positive pressure ventilation,keeping the overpressure of the anterior at 25～30 Pa,and a class A fire door is necessary; the overpressure of refuge walkway should also be 25～30 Pa.
