It is well known that the generation of excess pore water pressure and/or liquefaction in foundation soils during an earthquake often cause structural failures. This paper describes the behavior of a small-scale braced wall embedded in saturated liquefiable sand under dynamic condition. Shake table tests are performed in the laboratory on embedded retaining walls with single bracing. The tests are conducted for different excavation depths and base motions. The influences of the peak magnitude of the ground motions and the excavation depth on the axial forces in the bracing, the lateral displacement and the bending moments in the braced walls are studied. The shake table tests are simulated numerically using FLAC 2D and the results are compared with the corresponding experimental results. The pore water pressures developed in the soil are found to influence the behavior of the braced wall structures during a dynamic event. It is found that the excess pore water pressure development in the soil below the excavation is higher compared to the soil beside the walls. Thus, the soil below the excavation level is more susceptible to the liquefaction compared to the soil beside the walls.

众所周知，地震期间基础土壤中过高的孔隙水压力和/或液化的产生通常会导致结构破坏。本文描述了在动态条件下嵌在饱和可液化沙子中的小尺寸支撑墙的性能。振动台测试是在实验室中通过单支撑在嵌入式挡土墙上进行的。针对不同的挖掘深度和基本运动进行测试。研究了地震动峰值和开挖深度对支撑中轴向力，支撑壁中的横向位移和弯矩的影响。使用FLAC 2D对振动台测试进行数值模拟，并将结果与​​相应的实验结果进行比较。发现土壤中产生的孔隙水压力会在动态事件中影响支撑墙结构的行为。发现在开挖下方的土壤中，多余的孔隙水压力比在围墙旁边的土壤中要高。因此，与围墙旁边的土壤相比，开挖水平以下的土壤更易于液化。
