This paper presents experimental results from shaking table tests on two reduced-scale geogrid reinforced soil retaining wall (RSRW) constructed using standard soil, modular facing blocks, and uniaxial geogrid reinforcement to investigate the distribution of the lateral displacement, observe the failure mode of the RSRW, and analyse the lateral displacement control index under seismic loading. Similitude relationships for shaking table tests in a 1 g gravitational field were used to scale the specimen geometry and characteristics of the earthquake motions. The displacement modes of two RSRW are combined translation and rotation. Considering various displacement control indexes and the test results, a lateral displacement control index of 3.8% H in seismic damage of modular-block RSRW is proposed. The seismic damage-assessment criteria of the modular-block RSRW are defined and divided into four levels: basically intact, slightly damaged, moderately damaged, and destroyed.

本文通过振动台试验的结果，对使用标准土，模块化饰面砌块和单轴土工格栅加固的两个缩小规模的土工格栅加筋土挡土墙（RSRW）进行了研究，以研究侧向位移的分布，观察土工格栅的破坏模式。 RSRW，并分析地震荷载作用下的侧向位移控制指标。在1 g重力场中用于振动台测试的相似关系用于标定试样几何形状和地震运动的特征。两个RSRW的位移模式是平移和旋转相结合。考虑到各种位移控制指标和试验结果，提出了模块化块体RSRW地震破坏水平位移控制指标为3.8％H。
