“<strong>Dynamic</strong>s, Structural and Earthquake Engineering:Research and Practice”• Proliferation of commercial high-speed lines• Variety of new “old “ problems.• Bridge resonances produced not only by critical speeds but byrepeated excitation by the axle loads.• Ballast liquefaction due to high levels of vertical acceleration• Deagregation of embankments on soft soils due to wavestravelling to speeds near the train one.• Vibration ( and sound!) transmitted to nearby buildings.16 - july - 2010ENRIQUEALARCÓN1.
