Abstract

In order to study dynamic response and deterioration law of ballast bed under long-term repeated train load, the discrete element analysis software PFC was used to establish the discrete element computation model of ballast bed considering ballasts’ true shape, crushing and degradation to analyze vibration responses of ballast bed, forces exerted on ballasts, ballasts’ friction energy-dissipating and crushing behavior under cyclic loads with different frequencies and amplitudes. The results showed that ballasts’ vibration acceleration increase nonlinearly with increase in dynamic load’s frequency and amplitude; contact forces exerted on ballasts are mainly affected by load amplitude, load frequency has a smaller influence on them, the larger the load amplitude, the bigger the ballasts’ contact forces; increase in load amplitude or frequency can add ballasts’ friction energy-dissipating, in initial stage of load acting, ballasts’ friction energy-dissipating has a sudden growth process; load amplitude is the dominant factor on crushing behavior of ballasts, ballasts stay at a lower crushing level when load amplitude is lower; when load amplitude is higher, ballasts’ crushing phenomenon intensifies and is affected by load frequency, the higher the load frequency, the more serious the ballasts’ crushing this moment.
