A method of stratified monitoring and analysis of pavement settlement under the dual action of static and dynamic loads is proposed.The road surface data was obtained using a laser scanner and a road surface data model was constructed.The chromatography of road surface settlement under static and dynamic loads was analyzed.The weight of road settlement observation under dual loads is calculated through probability function factor weighted processing.Evaluate the trend and degree of road settlement through numerical simulation analysis under the dual effects of static and dynamic loads.The results show that the error between the monitoring settlement under static load and the actual settlement is less than 0.02 mm,and the error between the monitoring settlement under dynamic load and the actual settlement is less than 0.04 mm.It can provide the basis for monitoring of road settlement under different load conditions(static and dynamic).
