| Abstract: | Through detailed detection of a certain slant-legged rigid-frame arch bridge,this paper carries out evaluation of technical performance of bridge operation,studies out its reinforcement measure as changing slightly curved plate member,strengthening deck pavement,and crack closure on the basis of the evaluation and through structural checking computations,in order to increase the operation safety of the bridge and prolong its service life. |
