摘　　要：分析虹吸式屋面雨水系统常规设计方法存在的局限性,提出采用更精确的计算方法来模拟系统的水力状况,充分考虑支流汇入悬吊管对系统造成的水力影响。对虹吸式屋面雨水系统进行实例计算,在节点压强、管内压力变化趋势等方面,与常规计算方法作对比分析,结果表明,精确计算方法的结果更为合理,为虹吸式屋面雨水系统设计提供了新的思路。The limitations of conventional design methods of siphonic drainage systems of roof were analyzed. More precise calculation method to simulate the system hydraulic conditions was proposed. The hydraulic impact caused by tributaries into hanging pipe on the system was fully considered. A case calculation of siphonic drainage systems of roof was carried out, and the accurate calculation method was compared with the conventional method in node pressure, internal pressure change and so on. The results showed that the accurate calculation method was more reasonable and provided a new idea to design si- phonic drainage systems of roof.
