Abstract:After “5.12” Wenchuan earthquake, inspection and evaluation on 5 damaged bridges on “Lanzhou-Chengdu-Chongqing” Oil Pipeline were carried out. With an engineering example of Yangmu bridge which is the most badly damaged, the inspection contents and methods of concrete hollow slab beam bridge were discussed. The structure models were builded for calculation and anylysis by the application of finite element analysis software. Then the load-carrying capacity was evaluated totally based on the above results. Recommendations of repair and reinforcement on girders, supports, bent cap, etc. were proposed, and the experience and defects of current inspection and evaluation were summarized. Further more, the application and development of bridge inspection and evaluation were discussed，and some suggestions for aseismatic design of bridges such as restricting the displacement of girders were put forward.
