By virtue of its high speed, steadiness, and quality experience, high speed railway (HSR) has grown rapidly. During that development, problems such as dynamic irregularity in the bridge–embankment transition have been exposed and have aroused keen attention. To study dynamic performance in bridge–embankment transition, field dynamic tests under 120 high speed vehicles running at speeds of 5–360 km/h were carried out. Then, processed signals were obtained from the original signals by a series of signal processing methods such as wavelet soft ...
