    摘要:

    机场跑道排水是保障飞机运行安全和飞机品质的关键因素之一,良好的排水系统能够有效排除雨水,减少积水和滞留水的影响。为了探讨现有机场跑道排水系统排水能力,以及降雨与排水系统的演化过程,文章以国内某机场跑道为研究对象,将DHI MIKE模型应用于机场跑道,构建耦合雨洪模型。根据研究区域的降雨特性以及现有排水系统,设计四种不同重现期的降雨情景,从管道充满度、地表淹没结果、跑道积水演化过程三个方面进行模拟分析。结果表明:管道满管数量与降雨强度呈正比关系,不同重现期下研究区域水深的空间分布大体呈一致状态,集中在集水浅沟周围。重现期越大,积水深度越高;出现积水时间和跑道关闭时间提前。跑道排水能力基本能够满足5年一遇的降雨标准。

    Abstract:

    Airport runway drainage is one of the key factors ensuring the safety and quality of aircraft operations. A well-functioning drainage system effectively removes rainwater and minimizes the impact of water accumulation and stagnation. In order to investigate the drainage capacity of the existing airport runway drainage system and the evolution process of rainfall and drainage systems, this study focuses on a domestic airport runway and applies the DHI MIKE model to simulate the runway using a coupled rainfall-flood model. Based on the rainfall characteristics of the study area and the existing drainage system, four different recurrence interval rainfall scenarios are designed to analyze the pipe filling rate, surface submergence results, and runway water accumulation process. The results indicate that the number of pipes filled with water is positively correlated with rainfall intensity. The spatial distribution of water depth in the study area remains consistent across different recurrence intervals, mainly concentrated around shallow drainage channels. As the recurrence interval increases, the water depth increases, leading to earlier occurrence of water accumulation and runway closure. Overall, the runway drainage capacity is able to meet the rainfall standards of a 5-year recurrence interval.
