In this paper, the shear strain-dependent dynamic response properties of a retaining wall model made of mechanically stabilized earth (MSE) with polymeric geostrip material are investigated in a 1-g shaking table test. The values of lateral displacements and accelerations measured at different points along the MSE wall surface were used to evaluate the equivalent hysteris loops. The effect of reinforcement stiffness and backfill slope angle on the equivalent shear stiffness modulus ($G_e$) and damping ratio ($D$) were investigated. The experimental results show that the variation of shear stiffness modulus and damping ratio as a function of shear strain (γ) is affected by vertical pressure (σ_v), but the effect of the stiffness of the polymeric geostrip on the damping ratio is negligible. The variations of the $G_e$, $G_e/{\sigma }_v$, $G_e/G_{\mathit{max}}$, and $D$ as a function of γ are expressed in exponential equations with high least squares values in this study.

在本文中，在 1 g 振动台试验中研究了由机械稳定土 (MSE) 和聚合物土工带材料制成的挡土墙模型的剪切应变相关动态响应特性。沿 MSE 壁表面不同点测量的横向位移和加速度值用于评估等效磁滞回线。钢筋刚度和回填坡度对等效剪切刚度模量的影响（$G_e$）和阻尼比（$D$）进行了调查。实验结果表明，剪切刚度模量和阻尼比随剪应变（γ）的变化受到竖向压力（ σv _）的影响，但聚合物土工胶带的刚度对阻尼比的影响可以忽略不计。的变化$G_e$,$G_e/{\sigma }_v$,$G_e/G_{\mathit{最大限度}}$， 和$D$在本研究中，作为 γ 的函数，用具有高最小二乘值的指数方程表示。
