【 摘 要 】

A concrete simply supported T-beam bridge in a rural highway in a county of Yunnan, China, has been found to have a large number of cracks in the T beam when it is tested. Most of them belong to the non structural cracks. The vertical cracks in the middle part of the 1# bent beam of the substructure were seriously damaged and the bearing capacity was low. The bridge was assessed as the IV bridge, and its cracks and other diseases were disposed after research. After the reinforcement is completed, the test shows that the bearing capacity of the bridge has been restored and improved, and the measures adopted are also effective, which can provide some reference for the reinforcement of the same type of bridge.
