Damage of pavement over corrugated steel plate culvert with shallow cover was analyzed by filed investigation and numerical analysis. Field measurement showed that the flexible culvert was within the deformation limit and was structurally stable. Numerical analysis showed that deformation of culvert at the crest during the passage of heavy vehicle was about 2.72mm while the thrust and moment within the structure was far below the allowable value. It is concluded that the pavement was damaged by the cyclic deformation of culvert by the heavy vehicle.
