路肩挡墙支护能力对路基面动变形有重要影响。构建高速铁路无砟轨道-路肩挡墙路基的空间结构有限差分模型,针对以倾覆破坏为主导模式的岩质地基重力式挡墙,基于正交试验方案,分析路堤高度、墙胸坡度、墙背倾斜、墙土摩擦、墙体位置、抗倾覆稳定系数共6个因素对路基承受列车荷载的动变形影响效应。通过引入反映路肩挡土墙约束路基能力的动变形指数R_ω,建立路基面动变形与显著影响因素之间的关系式。研究表明:列车荷载下路基面动变形以压缩变形为主,跟随变形与墙顶水平动位移近似呈线性正相关;挡墙抗倾覆稳定系数K_0和墙背倾斜tanα是影响路基面动变形的2个显著因素,R_ω与K_0和tanα之间服从二元三次曲面关系;以路肩挡墙路基面动变形ω不大于标准断面路堤相应值δ,即R_ω=δ/ω≥1.0为控制条件,墙背由俯斜渐变为仰斜,路肩挡墙抗倾覆稳定系数限值[K_0]非线性增大。研究成果对优化高速铁路路肩挡墙设计具有参考价值。
