Abstract

The purpose of this study was to clarify the influence of an impact load caused by a train passing over a rail joint on a prestressed concrete (PC) sleeper. In this study, we conducted a three-dimensional finite element (FE) model of the PC sleeper, which was able to simulate its nonlinear behaviour. Using this numerical analytical model, the influence of the impact load caused by the rail joint on the maximum bending moment and stress generated in the sleeper for various irregularities and train speeds were quantitatively evaluated. This study clarified the following items: 1) No cracks occurred in the PC sleeper under the rail surface irregularity actually measured in the field; 2) The crack generated owing to a train running at a speed of 87 km/h when the rail surface irregularity was three times the measured value (the maximum dimension of the irregularity was 7.05mm); 3) The bending moment of the PC sleeper had the characteristic of speed dependency, which was regarded as an influence of the rail surface irregularity
