摘要
介绍我国高速铁路桥梁联调联试特点和进展,包括试验目的、试验内容、试验设备和技术、评价规范等,基于对高速铁路桥梁动力性能测试数据的不断积累,重点分析和总结高速铁路桥梁联调联试中主要参数和变化规律,形成一整套高速铁路桥梁动力性能评价标准,为我国高速铁路40 m大跨度简支箱梁的优化研究提供理论支撑。
This paper introduces the characteristics and progress of integrated commissioning and test of highspeed railway bridges, including the purpose, content, equipment and technologies of the test and evaluation standards. Based on consistent accumulation of test data of high-speed railway bridge dynamic performance, the paper focuses on analyzing and summarizing the main parameters and changing rules in integrated commissioning and test of high-speed railway bridges, and ushers in a complete set of evaluation criteria for the dynamic performance of high-speed railway bridges, which will provide theoretical support for the optimization study of 40-m long-span simple-supported box girders of high-speed railways in China.
