Abstract: Based on Abaqus software, a simulation model for hydroplaning on airport asphalt pavements was developed by the coupled Eulerian-Lagrangian (CEL) method. The influence rules of factors such as tire load, tire pressure, pavement texture and water film thickness on hydroplaning behavior were systematically analyzed through controlled variable approach, and a prediction model for critical hydroplaning speed was constructed via multiple linear regression. The research results indicate that the established CEL model can effectively simulate the tire-pavement-water interaction. When an aircraft lands on a wet runway, if the water film thickness exceeds 8mm and the slip ratio is below 10%, braking is required to increase the slip ratio to mitigate the risk of hydroplaning. Under extremely wet conditions, the pavement gradation optimization should comprehensively consider factors such as texture depth and pavement connectivity. The established model clarifies the influence of key parameters, including water film thickness, tire load and pavement texture, providing a quantitative basis for the anti-skid design and safe operation of asphalt pavements.
