Lateral earth pressure on rigid retaining walls with EPS deformable geofoam inclusions

  • 摘要: 建立有限差分数值模型对设置EPS(发泡聚苯乙烯)柔性垫层的刚性挡土墙的土压力进行研究,分别对挡土墙后填土的静止、主动及被动三种位移状态进行了研究,并对不同挡土墙位移时EPS垫层减小土压力的效果进行了分析。研究结果表明:EPS对主动状态所需要的位移影响较小。静止-主动状态时,EPS减小土压力的效果随着位移的增大而减弱;静止-被动状态时,EPS减小土压力的效果随着位移的增大先增强后减弱。
    Abstract: The finite difference program, FLAC3D, is used to model the rigid retaining wall with EPS (expanded polystyrene) deformable geofoam inclusions, and the lateral earth pressure on the wall is obtained from numerical results. The at-rest state, active state and passive state of the retained soil behind the wall are studied, and the reductions of EPS on the lateral earth pressure with different wall displacements are also analyzed. The results indicate that EPS has little influence on the wall displacement required by the active state. The reduction of EPS on the lateral earth pressure decreases with the increase of the wall displacement in the retained soil between at-rest state and active state, while that increases firstly and then decreases with the increase of wall displacement in the retained soil between at-rest state and passive state.
