摘　　要：在大型钢结构屋面的虹吸雨水系统设计中,天沟尺寸和溢流口设计对屋面雨水的安全排放至关重要。本文针对目前虹吸雨水系统天沟尺寸计算方法不足和溢流口设置方式单一的问题,结合工程实例对其进行水力计算分析,提出合理的天沟尺寸计算方法和组合式溢流系统,以期可为类似工程提供参考。In the design of siphonic drainage system in large steel structure roof,the design of gutter size and over flow port is critical to the safe discharge of the rainwater on roof.Aiming at the problem of the lack of calculation methods of the gutter size and dull setting mode of over flowport,the hydraulic calculation is carried out combing with the engineering project,and reasonable calculation methods of the gutter size and combined overflow system are given,which is expected to provide references for similar projects.
