摘要
以一座重载铁路桥梁加固工程为实例,结合加固前、后的桥梁动载试验,综合分析比较了各次测试的动力反应。测试结果表明,桥梁加固后横向振幅满足规范限值要求,加固效果明显。该工程的试验研究结果对同类重载铁路桥梁的检测加固实践具有参考价值。
Taking a heavy haul railway bridge reinforcement project as an example with the analysis and comparison of the bridge dy- namic load test before and after reinforcement, and comprehensive dynamic response of each test, it shows that reinforced bridge transverse amplitude meeting the specification limits, and that the reinforcement effect is obvious. This experimental study has a reference value for similar heavy haul railway bridge detection and reinforcement.
