摘要 针对交通荷载作用下的水平-竖向(Horizontal-Vertical,H-V)加筋路堤,利用有限元软件ABAQUS建立二维模型并对路堤进行显示动力分析.通过动三轴试验,将其结果拟合成应变软化曲线并编入ABAQUS用户子程序,同时,对不加筋、水平加筋和H-V加筋3种工况下的路堤变形和应变进行比较.结果表明:在交通荷载作用下,H-V加筋路堤能够显著减小路堤的竖向位移和水平位移;H-V加筋能够控制路堤的不均匀沉降,减小应变,而且较普通的水平加筋效果显著,尤其在水平位移的约束方面. In order to study the embankment reinforced with Horizontal-Vertical (H V) reinforcement un der traffic loading, a two-dimensional model was calculated by finite element method (FEM) program ABAQUS using dynamic explicit. According to the result of dynamic triaxial tests, fitting strain-softening curve was written into user subroutine in ABAQUS. The deformation and strain of the embankment with- out reinforcement, with ordinary reinforcement and with H-V reinforcement were analyzed and compared. The H V reinforcement significantly reduced the strain, vertical displacement and horizontal displacement and controlled differential settlement in embankment under traffic loading. H-V reinforcement had a better reinforced effect than ordinary reinforcement, especially in the control of horizontal displacement.
