Mechanism of Sleeper–Ballast Dynamic Impact and Residual ...
The ballast quasistatic loading analysis indies an increase of more than 2 times in the ballast loading in neighbour zones for long voids and almost full quasistatic unloading for shortlength voids. However, the used imitation model cannot explain the nature of the dynamic impact. The mechanism of the void impact is clearly explained by the analytic solution using a simple clamped beam. A ...
