摘　　要：在PFC中建立双轨距轨枕-道床的离散元仿真模型,分析其道床阻力特征。在现场相同工况下进行轨枕实尺模型的道床阻力测试。研究结果表明,提高双轨距轨枕所受道床横向阻力的最有效方法是增大轨枕端面面积和底面积。A discrete element simulation model of double-gauge sleeper-roadbed is established in PFC to analyze its roadbed resistance characteristics.Under the same working condition in the field,the paper carries out the bed resistance test of the real scale model.The research results show that the most effective way to improve the lateral resistance of double-gauge sleepers is to increase the end face area and bottom area of the sleeper.
