Effect of Geogrid Arrangement and Rigid Rc Facing on the Mechanical Behavior of Geosynthetic-Reinforced Soil Retaining Walls Under Trainloading

Key Points

• This research aims to investigate how the arrangement of reinforcement materials and the presence of rigid facing affect the mechanical behavior of soil retaining walls under dynamic train loading.
• Conducted dynamic loading tests on full-scale models of reinforced soil walls.
• Utilized finite element analysis to assess the behavior of wall configurations under loading conditions.
• Evaluated vertical spacing of reinforcement materials and the effects of rigid facing presence.
• Rigid facing with wider spacing of reinforcements showed similar subsidence trends to general earthworks.
• Without the wall face, significant deformation occurred, differing from scenarios with a rigid face.
• Finite element analysis accurately replicated the behavior of rigid-faced reinforced soil walls under dynamic loading.
