| 摘 要： | 高速动车组地板结构作为重要的防火隔断之一,其耐火性能在火灾的发展中起着重要的作用。对高速动车组地板结构在标准温升曲线下的耐火性能进行了数值模拟,并与地板结构耐火试验的结果进行了对比。结果发现,30 min内地板结构数值模拟结果具有较好的复现性,30 min后地板结构在高温下的破坏形式与试验存在较大差异。

| Abstract: | High-speed EMU floor structure is one of the important fire-resistive partitions,the fire resistance performance of which plays an important role in stopping the expansion of fires.Numerical simulation of the fire resistance performance of high-speed EMU floor structure under standard temperature rise curve is conducted and is compared with the results of standard structure fire furnace test.Results show that the numerical simulation is a good replication of the test within 30 minutes,however after the period,large gap exists between simulation and test in terms of floor structure destruction under high temperature. |
