As the vital point of road transportation, the bridges have become the vinculum that promotes the development of region economy. In the long-term usage, the bridge structure would be damaged by many external factor such as environment, overloading, etc.These damages will reduce the bridge structure" resistance and cause potential safety hazard.It¡¯s unpractical to dismantle thousands of these bridges totally and the fund of rebuild them is extremely huge amount. The situation of our country request that we should examine, maintain and reinforce the existing bridges in the meantime build new bridges, to promote the old bridges¡¯traffic condition and loading capacity. Therefore, how to test these existing bridges¡¯technical condition and loading capacity rapidly, accurately, and scientifically has been a most important domain in the bridge engineering field.According to many documents, this text discusses the detection content of concrete bridge, analysises the advantage and disadvantage of various detection methods, puts forward the suitable detection method of concrete bridge. It also valuates the QunYing River bridge on North Democracy Road, mades detection conclusion, and comes up with disposal method targeted. Especially, it provides the train of thought and method reference in detection field of the servicing concretes bridge.
