| Abstract: | The influence to the safety of the bridge is studied after a freighter bumped into one of its piers. The emulation and analyses technology of the computer is adopted to simulate the deformation and stress situation of the pier after a freighter bumps into it. Corresponding modeling method and dealing means are used according to the fracture situation of the pier, thus the extent of damage and impact on safety performance of the bridge are the possible reflected, which offers basis for safety assess. |
