In this study, the failure mode of flexible reinforced soil slopes under earthquake action was investigated by shaking table tests. The distribution law of a potential failure surface of a flexible no-faceplate reinforced soil slope under earthquake action was obtained based on the analysis results. A simplified trilinear failure surface suitable for flexible reinforced soil slopes without faceplate was proposed. Subsequently, based on the upper-bound theorem of limit analysis, we derived the formula for calculating the yield seismic acceleration coefficient of a flexible no-faceplate reinforced soil slope under a seismic load. The main parameters that affect its seismic performance were determined. The flexible geogrid reverse-packed reinforced earth structure can effectively limit the fracture of a slope body and improve the stability of the slope. This provides a theoretical basis for facilitating the engineering of flexible reinforced soil slopes.

柔性土工格栅包裹加筋土坡的抗震性能

通过振动台试验研究了柔性加筋土边坡在地震作用下的破坏模式。根据分析结果，得​​出了无面板柔性加筋土边坡在地震作用下的潜在破坏面分布规律。提出了一种适用于无面板柔性加筋土坡的简化三线性破坏面。随后，基于极限分析的上限定理，推导了计算无荷载作用下柔性无面板加筋土边坡屈服地震加速度系数的公式。确定了影响其抗震性能的主要参数。柔性土工格栅反填充加筋土结构可以有效地限制边坡体的断裂，提高边坡的稳定性。这为简化柔性加筋土坡的工程设计提供了理论基础。
