叙述了大型公共建筑疏散设计的重要性及疏散时间设计计算要点,确定看台出入口、楼梯及外门疏散口宽度和总疏散时间设计计算的思路,尝试当前后疏散口宽度、数量不同时,疏散计算的疑难点即确定加权平均距离的方法,通过实例计算清晰显现了其全过程。 The importance of evacuation design of large-scale public buildings and the key points in the design of evacuation time are described. The design and calculation of evacuation width and total evacuation time at the entrances and exits of the grandstands and staircases and exterior doors are determined. At the same time, the evacuation calculation Difficult point that is to determine the weighted average distance method, through example calculation clearly shows the whole process.
