土工合成材料加筋土边坡在我国西藏高海拔强震区基础设施建设中的应用正逐渐增加，不同坡面形式在加筋土边坡遭遇地震时发挥的保障效果各异，但以往针对不同坡面形式加筋土边坡抗震性能的研究较为缺乏。因此，本文通过开展土工袋和格宾笼护坡的加筋土边坡振动台模型试验，研究不同地震峰值加速度作用下坡面形式对土工格栅加筋土边坡动力响应特征的影响，重点关注地震作用下边坡加速度放大系数、坡面位移、坡顶沉降以及筋材轴力等分布规律。试验结果表明，加筋土边坡各处加速度放大系数均随高度的增大而增大，坡面形式对加速度放大系数的影响很小；整体上坡面峰值位移随高度增加而逐渐增大，除边坡顶部外，格宾笼组峰值位移小于土工袋组，且震后坡面位移得到了一定程度的恢复；坡顶沉降随地震峰值加速度的增大逐渐增大，格宾笼组的坡顶沉降大于土工袋组；土工袋组筋材轴力整体上大于格宾笼组，地震作用下顶部筋材轴力增量最大；在1.0g地震峰值加速度下，采用土工袋及格宾笼护坡的土工格栅加筋土边坡均具有良好的抗震性能。

Geosynthetic-reinforced soil (GRS) slopes are increasingly being utilized in infrastructure construction in the high-altitude, seismically active regions of Tibet, China. There are varying protective effects of different slope face patterns during earthquakes. However, research on the seismic performance of GRS slopes with different slope face patterns remain limited. This study conducted shaking table model tests on GRS slopes with soilbags and gabion meshboxs as slope face patterns to study the influence of slope face patterns on the dynamic response characteristics of GRS slope. The focus was on examining the distribution of acceleration amplification factors, slope displacements, slope settlements, and geogrid axial forces under seismic loads. The test results show that the acceleration amplification factors increase with height across all GRS slopes, with minimal impact from different slope face patterns. Generally, the peak displacement of the slope surface increase with slope height. Except for the top, the peak displacement of the gabion meshbox group is smaller than that of the soilbag group, and the post-seismic displacement showes partial recovery. Slope settlement increase with rising PGAs, with the gabion meshbox group experiencing greater settlement than the soilbag group. The geogrid axial force of the soilbag group is generally higher than that of the gabion meshbox group, with the maximum geogrid strain increments occurring at the top of the slope due to seismic action. Under a PGA of 1.0g, both the geogrid reinforced soil slopes using soilbags and gabion meshboxs as slope face patterns demonstrate excellent seismic performance.
