Experiment and DEM Analysis of Lateral Resistance of Glued Ballast

  • 摘要: 为揭示胶粘道床横向阻力的工作机理,在高速铁路胶粘道床路段进行了横向阻力现场试验.分析了胶粘道床横向阻力的变化特征;利用离散元软件PFC3D(particle flow code in 3 dimensions)建立了胶粘道床三维模型,对胶粘道床内部接触力、应力进行了统计分析.研究结果表明:用胶状态下胶粘道床横向阻力值是有砟道床规范值的4.6倍,横向阻力提升显著;胶粘道床在提升横向阻力的同时,轨枕-道砟接触点压力值最大为1.2 KN,平均值为112.48 N,道砟仍处于良好的受力状态;道床全断面粘结时应保证枕下26 cm范围道砟胶喷涂的充分和均匀,以确保道床粘结效果的发挥;胶粘道床不同位置对横向阻力的分担比相对于有砟道床变化明显,胶粘道床枕侧承担63%、枕底承担24%、砟肩承担13%.
