采用简化的刚体离散元数值模型，研究了干石砌块挡土墙在平面应变下的失稳问题。这项研究最初集中在模拟以前报道的墙体行为的实验数据，然后评估参数变化对稳定性的影响。考虑了砌体特性(墙缝剪切刚度、法向刚度、抗拉强度和砌块几何形状)、回填特性和整体墙几何形状的影响。将试验研究和数值模型的结果与极限平衡分析结果进行了比较。
A simplified rigid block distinct-element numerical model is used to investigate the instability of dry-stone masonry retaining walls in plane strain. The investigation initially concentrates on modeling previously reported experimental data of wall behavior and thereafter assesses the influence of parametric variation on stability. Influence of masonry characteristics (wall joint shear stiffness, normal stiffness, tensile strength, and block geometry), backfill properties, and overall wall geometry are considered. Results from the experimental study and numerical model are compared with a limit equilibrium analysis.
