摘　　要：国内虹吸式屋面雨水系统在设计过程中,往往是绘图设计与水力计算分离进行,而水力计算复杂且工作量大,更缺乏有效的支持工具。采用计算机辅助设计手段,通过管系建模,并巧妙设置水力计算的参数初值及合规验算的次序与方法,借助“允许管径矩阵表”,可以快速自动完成管径推算,省时省力地高效率生成最简省的虹吸式屋面雨水系统设计方案。In the design process of domestic siphon roof rainwater drainage system, drawing design and hydraulic calculation are often separated, and hydraulic calculation is complex and workload is large, but lack of effective support tools. By means of computer-aided design, piping system modeling, and skillfully setting the initial values of hydraulic calculation parameters and the orderand method of compliance checking, and with the help of the "allowable pipe diameter matrix table", the calculation of pipe diameter can be completed automatically and quickly, and an optimal and economical siphon roof rainwater drainage system designscheme can be generated efficiently and time-saving.
