This article examines the stability of retaining walls with relief shelves compared to the conventional cantilever wall using limit analysis integrating with the finite element method. The performance of such walls subjected to an incremental static uniformly distributed surcharge loading on the backfill surface is accessed in the terms of the magnitude of the surcharge carrying capacity of the walls before the incipient failure of the overall structure. From the analysis, it is noted that the provision of an appropriate number of relief shelves and their suitable locations and widths to the wall can bring significant improvement in the stability of the retaining wall compared to a wall without a relief shelf. Furthermore, it is noted that the width and location of the relief shelf are the major governing factors that are susceptible to modify the shape of the potential failure plane, the failure mode of the wall, and the backfill surface settlement profile. To maximize the stability of the wall subjected to static loading on the backfill surface, recommendations are laid for the optimum location and width of the relief shelves for a given height of the wall.

本文使用结合有限元方法的极限分析，检验了带有浮雕架的挡土墙与传统悬臂墙相比的稳定性。此类墙在回填表面承受增量静态均匀分布的超载载荷时的性能，可根据整个结构初期失效前墙的超载承载能力的大小来评估。从分析中可以看出，与没有浮雕架的墙相比，提供适当数量的浮雕架以及它们对墙壁的合适位置和宽度可以显着提高挡土墙的稳定性。此外，值得注意的是，减压架的宽度和位置是容易改变潜在破坏面形状、墙体破坏模式和回填表面沉降剖面的主要控制因素。为了最大限度地提高墙体在回填表面承受静载荷的稳定性，建议针对给定的墙体高度确定减压搁板的最佳位置和宽度。
