摘　　要：极端强降雨会造成机场跑道道面积水现象,道面水膜的存在会导致飞机极易发生滑水安全事故。基于二维浅水方程,根据机场跑道的特点,研究了影响道面水膜厚度的因素,并提出一种基于二维浅水方程预测降雨条件下道面水膜厚度的方法,与现有经验模型计算结果进行对比,证明了模型的准确性,对机场管理部门雨天进行跑道管理具有参考意义。Extremely heavy rainfall will cause the water phenomenon of the airport runway area,and the existence of the water film on the road surface will cause the aircraft to easily occur water skiing accidents.Based on the two-dimensional shallow water equation and the characteristics of the airport runway,the factors affecting the water film thickness of the road surface are studied,and a method for predicting the water film thickness of the road surface under rainfall conditions based on the two-dimensional shallow water equation is proposed.The comparison of the results proves the accuracy of the model,which has reference significance for the airport management department to conduct runway management in rainy days.
