The requirement of fire separation between the high-rise buildings was discussed based on the practice work and requirement of fire fighting. The relation between the distance from the inner side of fire road to the side wall of high-rise building and the height of high-rise building for the fire vehicle to work was discussed. How to ensure the fire vehicle to work when the high-rise building is higher than 50 m was discussed. The fire separation must larger than 16 m when the high-rise building is higher than 50 m, and the fire separation is in 9～15 m when the high-rise building is lower than 50 m.%结合工作实际,从满足消防扑救角度探讨高层建筑物之间应满足的防火间距.对登高消防车能正常展开工作时消防车道内边距建筑高层主体外墙距离与建筑高度的对应关系进行了探讨,对建筑高度超过50 m时如何保证消防车正常工作进行了探讨.高层建筑高度大于50 m时至少应预留16m的防火间距,高层建筑高度小于50 m时预留9～15 m防火间距.
