中文摘要:

导致火车的地面颤动上的分析的发展简短被总结。train-track-ground 综合动态模型在纸被介绍预言高速度的火车导致的扎根的颤动。模型预言的 train-track-ground 系统的代表性的动态回答被介绍。在二列高速度的火车导致的扎根的颤动上从二地测试测量的一些主要结果被报导。与建议 train-track-ground 模型一起的数字预言被运用实验的高速度的火车验证。研究结果证明动态相互作用由轨道不规则引起了的车轮 / 栏杆在扎根的排水量上的扎根的加速和小影响上有重要影响。高速度的火车导致的扎根的颤动的主要频率通常在 80 Hz 下面。与 ballasted 轨道相比,无碎石的轨道结构能在 40 Hz 上面在频率生产许多更大的导致火车的地面颤动。垂直地面颤动比侧面、纵的部件大得多。

英文摘要:

The development of analysis on train-induced ground vibration is briefly summarized. A train-track- ground integrated dynamic model is introduced in the paper to predict the ground vibration induced by high-speed trains. Representative dynamic responses of the train-track-ground system predicted by the model are presented. Some major results measured from two field tests on the ground vibration induced by two high-speed trains are reported. Numerical prediction with the proposed train-track-ground model is validated by the high-speed train running experiments. Research results show that the wheel/rail dynamic interaction caused by track irregularities has a significant influence on the ground acceleration and little influence on the ground displacement. The main frequencies of the ground vibration induced by high-speed trains are usually below 80 Hz. Compared with the ballasted track, the ballastless track structure can produce much larger train-induced ground vibration at frequencies above 40 Hz. The vertical ground vibration is much larger than the lateral and longitudinal components.
