摘　　要：《建筑防烟排烟系统技术标准》GB51251-2017自2018年8月1日实施至今将近一年,地下走道(两侧为储藏间)排烟系统设计,包括防烟分区的划分,防烟分区面积计算,排烟量计算,排烟口设置,防火阀设置等,出现了多种设计方法。针对不同的工程设计方法,本文从规范制定背景,工程设计案例,各专业协调配合等方面进行了分析。Since the implementation of“Technical standard for smoke management systems in buildings”(GB51251-2017)on August 1,2018,it has been nearly a year,and the design of smoke exhaust system of underground corridor(both sides of which are storage rooms),including the division of smoke prevention zone,calculation of smoke prevention zone area,calculation of smoke exhaust volume,smoke exhaust port setting,fire valve setting,etc.,have emerged various design methods.From the background of specification formulation,engineering design cases and the coordination and cooperation of various majors,the different design methods were analyzed.
