摘要
随着轨道交通发展,轨交线路成为城市空间网络的主要动脉,也由单一站点向多线交织甚至多种交通方式换乘的趋势发展。这种大型枢纽公共空间如何在保证枢纽公共空间连续、通透的前提下,将防火分区划分为若干防火单元,降低火灾危险性成为大家关注的重难点之一。通过实例论证提出用防火隔离带划分防火单元的方法,并提出防火隔离带设置的相关建议。
With the development of rail transit,rail transit lines have become the main arteries of the urban spatial network.And they have also developed from a single station to multi-line interweaving or even multiple modes of transportation.How to divide fire compartment into several fire protection units on the premise of ensuring the continuity and transparency of the public space of the hub,and reducing fire risk has become one of the major difficulties that everyone pays attention to.Through the example demonstration,the method of dividing the fire protection unit with the fire protection isolation belt is put forward,and the relevant suggestions for the setting of the fire protection isolation belt are put forward.
