| 摘 要： | 支座是铁路桥梁的重要组成部分，它支撑着桥梁和过往列车的全部重量，以及列车的动荷能量，它在起到支撑和固定梁体的同时，还要起到梁体在受外力变形和受温度变化而变形时的自由伸缩的调节作用，铁路桥梁在运营过程中，支座在列车荷载作用下，支座底面与桥墩支撑垫石均会受到巨大的动能冲击。着重讨论高铁箱梁支座钢板空响的痛害预防与补救措施，对高铁箱梁支座预埋钢板产生空响的原因与可能导致的危害进行逐一深入分析，研究预防与补救高铁箱梁支座钢板发生空响可行措施。

| Abstract: | Support,an important part of railway bridge,bears the overall weight of bridge and passing train as well as the dynamic energy of the train.As the support and secure of the bridge,it also plays an important role in adjusting the deformation under exterior force and temperature with its own flexibility.In operation,under the weight of train,the bottom of the support and bridge pillar cushion stone bear enormous dynamic impact.The article mainly discusses the prevention and remedy high speed railway box girder sounding and analyzes in detail the causes and ensuing harm and its feasible counter measures so as to contribute to the technical improvement of railway bridge construction in China. |
