摘　　要：传统的屋面雨水系统即半有压流屋面雨水系统适用于各类工业和民用建筑，是应用最普遍、时间最久的屋面雨水系统。结合首钢京唐热轧带钢主厂房的建筑设计实践，探讨屋面雨排水系统的水力计算，包括天沟、雨水斗、雨水管的选择等，力求使屋面雨排水设计合理化，满足功能、节省投资、提高效益。The traditional roof rainwater system - the semi-pressure-flow roof rainwater system suitable for all kinds of industrial and civil buildings is the most popularly applied and the most durable roof rainwater system. The present article, in view of the building design practice of the main building of Shougang Jingtang Hot Rolled Strip Plant, describes the hydraulic calculation of the roof rainwater drainage system, including selection of gutters, rainwater hoppers, downspouts and the like, in order for a rational design of roof rainwater drainage and to satisfy the functions, save investment and improve the benefit.
