摘　　要：随着社会经济的快速发展,城市雨水排除问题日益突出,原有雨水管道设计计算理论不断面临实践的挑战,亟待更新。理论分析表明,目前常用的雨水设计流量计算公式仅适用于重力流状态下的雨水管道设计,而并不适用于压力流状态。针对此问题,基于连续性方程和最大雨强公式,提出了适用于压力流状态的雨水管道流量计算新方法,改进了此种状态下雨水管道的设计,是对目前雨水管道设计计算方法的完善。As the rapid development of society and economy, urban storm drainage problems have become increasingly prominent. The old calculation principle of the storm sewer is facing challenges in practice and needs to be improved urgently. The theoretical analysis showed that the current storm flow formula was only suitable for the gravity flow, not for the pressure flow. Aimed at this problem, based on the continuity equation and maximum rainfall intensity formula, a new flow calculation method for the pressure flow was proposed to improve the design of storm sewer under pressure flow. The current meth- ods of storm sewer design and calculation were improved.
