Abstract :
In this paper, Reasons for bridge-head bump are presented; change the thickness of slab, the filling materials used for embankment, and the vehicle speed so as to conduct a comparative analysis by ANSYS FEM software. The corresponding changes of slab´s displacement and internal force, settlement and stress of foundation are analyzed, and a method for solution of bump is proposed in this paper, and this result can provide reliable reference database for design and construction.
