摘要
铁路虽有安全、量大、舒适、方便的优势 ,由于当前交通运输业竞争激烈 ,因此必须提高运行速度到 140 km· h- 1 或 16 0 km· h- 1 以缩短旅客在途时间。我国铁路桥梁均按 12 0 km· h- 1设计。
Although the railway is superior in safety,mass transportation,comfort and convenience,keen competition in the current carrying trade.Demands that the train speed should be increased to 140 km·h -1 or 160 km·h -1 to cut down the traveling time,though the railway bridges in China were designed for 120 km·h -1 .The changes that may happen to briage vibration and serviceability of runing trains on the bridge due to train speed raise as well as necessary countermeasures are studied in trains the paper theoretically and experimentally.
