摘 要: 根据建筑物内疏散通道上的走廊、楼梯间及其前室的入口、楼梯段等的宽度和楼梯前室的面积等数据,通过建立模型进行计算,以保证火灾时人们能在一定时间内疏散到安全区域。安全疏散计算是假设某一层发生火灾,预测该层人员全部疏散到下层,并校核疏散环节的安全性。一般以各层为单位进行校核即可,但也可根据建筑的规模、形状、使用性质等,只校核其一个分区的安全疏散或几层同时疏散,或整栋建筑物的安全疏散。
关 键 词: 安全科学;建筑物;安全疏散;疏散模型;计算方法

Abstract: In this paper, a model is established and calculation is performed according to width of corridor of evacuation exit, widths of entrances of staircase and its antechamber, stair flight width, stair antechamber area and so on to ensure that people can be evacuated to safe place within a certain time in fire. The safe evacuation calculation is based on the assumption that fire occurs on a floor, predicts that all the people on the floor are all evacuated to the lower floor, and checks the evacuation safety. The check step usually takes each floor as checking unit, but can also check safe evacuation of only one sub-area or simultaneous evacuation of several floors or the whole building.
