摘　　要：以某钢筋混凝土简支T梁桥为研究背景,首先对该桥的外观状况进行评定,然后结合桥梁荷载试验对该桥的实际工作状态进行研究。结果表明:该钢筋混凝土简支T梁桥建设年代久远,外观病害较为严重评定为四类桥梁,应进行大修或加固,且由桥梁荷载试验得知该桥的承载能力也不能满足《公路桥梁承载能力检测评定规程》(JTG/T J21—2011)要求。A reinforced concrete simply supported T-beam bridge is taken as the research background.Firstly,the appearance of the bridge is evaluated,and then the actual working state of the bridge is further studied by combining with the load test of the bridge.The results show that the reinforced concrete simply supported T-beam bridge has been built for a long time,and the appearance of the bridge is more serious,which is evaluated as four types of bridge,and should be overhauled or strengthened.Moreover,the bridge load test learned that the bridge bearing capacity cannot meet the requirements of the Highway and Bridge Bearing Capacity Testing and Evaluation Regulations(JTG/T J21—2011).
