摘要: 近年来,高速铁路在我国得到了快速发展,由高速列车引起的附近土体及建筑物的振动问题越发突出。而附近土体的振动问题直接影响铁路沿线土地的正常使用,如何测定铁路沿线的土体振动问题是关键。针对客运专线高速列车的特点,布置了动力响应检测点,测定了高速列车通过时各个测点的动力响应值,并利用傅里叶变换求得振动响应的频谱值,从而更直观的反应了振动衰减的特性,其可为高速铁路减震降噪方法的选择提供数据,亦可为我国高速铁路的设计提供一些参考。

Abstract: The effect of the high speed train induced vibrations on the adjacent structures becomes more prominent with the rapid development of the high speed rail in recent years. The vibration within the soil mass would likely affect the normal use of the land along the railway alignments. The key to resolve the vibration related problem is to accurately measure the vibration. Based on the characteristics of the passenger rail lines, the dynamic response sensors were reasonably arranged in order to measure the response of the high speed train induced vibrations at various locations. The vibration response spectrum was obtained throughout the Fourier Transformation. The vibration dissipation characters can be more explicitly observed from the response spectrum. The objectives of the vibration study are: 1) provide basic data for the high speed rail vibration mitigation measures; 2) provide reference data for the high speed rail design.
