摘　　要：近年来我国极端恶劣天气频发,多地曾遭到暴雨袭击。面对长时间、高强度的降雨,机场中个别下沉式区域的雨水排水是重中之重,尤其一些机场内部重要建筑或设备设施用房位于低洼地势区域内,其雨水系统更是尤为关键。北京大兴国际机场航站区雨水系统设计中,暴雨重现期的确定对于机场下沉式区域雨水系统的形成和雨水管网的构建非常重要。通过对北京大兴国际机场航站区雨水系统的设计,探讨、研究并确定了其下沉式区域的降雨重现期。In recent years, the cases of extreme weather happened increasingly frequent, many places have been hit by torrential rain. In face of long-lasting and high-intensity rainfall, the design of rain drainage system has become to be the top priority for some subsidence areas in the airport. Especially, since some important buildings and equipment rooms are located in those subsidence areas, the rain drainage system becomes particularly critical. In the design of rainwater system in the terminal area of Beijing Daxing International Airport, the determination of rainstorm recurrence interval is very important for the formation of rainwater system and the construction of rainwater pipe network in the subsidence area of the airport. Through the design of the rain drainage system in Beijing Daxing International Airport terminal area, this article discusses,studies and gets the conclusion of the recurrence interval of rainfall in subsidence areas of Beijing Daxing International Airport.
