摘　　要：本文根据国外在提高货车轴重对铁路轨道结构的影响方面的研究成果，以及开行大轴重货车的运营实践，并结合我国在此方面所开展的研究工作，探讨在我国货车轴重将逐步提高到25t的过程中，对铁路轨道结构应采取的加强与维修措施。This paper describes the operation practice of heavier axle load car in foreigncountries and the research work about the effect of increasing axle load of freight car on railway track at home and abroad. On these grounds, it proposes the necessary measures forstrengthening and maintaining Chinese railway track structure when the axle load of freightcar will gradually be increased to 25t.
