| 摘 要： | 旧桥的承载力评定是确定桥梁健康状态的重要内容,它决定桥梁可以继续使用还是需要进一步的加固维修甚至是拆除重建。通过采用现场检测结果结合《公路桥梁承载能力检测评定规程》(JTG/T J21-2011)的方法对现有钢筋混凝土旧桥进行承载能力评定,为以后的公路桥梁状态评估和养护维修工作提供参考。

| Abstract: | The bearing capacity evaluation of old bridge is important in the determination of health state of bridge.It can determine whether to continue to use the bridge or to perform further consolidation maintenance even demolition and reconstruction.Through the adopt of field test results and in combination with method in Specification for Inspection and Evaluation of Load-bearing Capacity of Highway Bridge(JTG/T J21-2011),bearing capacity evaluation is conducted on existing old reinforced concrete bridges,providing reference for future status evaluation and maintenance of highway bridge. |
