| Abstract: | The innovation and reuse of existing bridge not only increase economic benefits, but also give reliable guarantee for safety of train running. Based on the dynamic test to existing bridge before reinforcement and research on the design for reinforcement, this paper proposes the suggestion to the bridge reinforcement and puts forward the problems to be resolved in nest stage for Qingdao-inan Railway Line under reconstruction. |
