| Abstract: | This paper analyzes the cause of cracking in piers of a railway bridge;it provides a reinforcement design scheme for the crack whose depth is more than the thickness of the reinforced protective layer of the bridge pier,that is,using deep grouting firstly,then slotting on the surface and replacing the grout by using reinforced concrete.This paper also carries out finite element analysis of reinforcement design for Pier 20of the bridge by means of using general-purpose finite element software ANSYS 11.0. |
