Railway transition zones connecting conventional embankments and rigid structures, such as bridges and tunnels, usually degrade much faster than other railway sections. Efficient health condition monitoring of transition zones is important for preventative track maintenance. In this paper, a methodology for monitoring railway transition zones using acceleration measurements on multiple axle boxes (multi-ABA) of a passing train is presented. To showcase its capability, the measurements in the Netherlands, Sweden, and Norway are analyzed and discussed. It is found that different bridges and transition zones exhibit unique characteristics including dominant wavelengths and energy distribution. Based on these unique characteristics, the geometry and support conditions at different locations of a transition zone can be evaluated. Higher train speed makes the characteristics more pronounced. The results demonstrate that the multi-ABA measurement has the potential to evaluate and thus monitor the health conditions of various transition zones.

摘要

Railway transition zones connecting conventional embankments and rigid structures, such as bridges and tunnels, usually degrade much faster than other railway sections. Efficient health condition monitoring of transition zones is important for preventative track maintenance. In this paper, a methodology for monitoring railway transition zones using acceleration measurements on multiple axle boxes (multi-ABA) of a passing train is presented. To showcase its capability, the measurements in the Netherlands, Sweden, and Norway are analyzed and discussed. It is found that different bridges and transition zones exhibit unique characteristics including dominant wavelengths and energy distribution. Based on these unique characteristics, the geometry and support conditions at different locations of a transition zone can be evaluated. Higher train speed makes the characteristics more pronounced. The results demonstrate that the multi-ABA measurement has the potential to evaluate and thus monitor the health conditions of various transition zones.
