本研究利用層狀剪力砂箱與移動式霣落器在震動台施作底土300mm高，其上為一垂直回包式加勁牆，長、寬、高為900mm×500mm×500mm，使用土壤材料為南投縣眉溪中上游河砂試體單位重γ_d=15 kN⁄m^3 ，藉由改變輸入地震波頻率條件、牆前邊坡角度及加勁材料長度以探討加勁牆體在地震力作用之下之牆體變位狀況、牆體加速度反應情況、加勁材料受力分布情況及地震波之能量，並將試驗結果與過往學者結果相並討論。
由震動台模型試驗結果可知:一、加勁牆體在地震中之變位深受震波頻率的影響，其牆面變位隨著頻率的降低而增加，從地震波之速度與能量差異可以看到影響。二、本研究之正規化牆體變位之曲線落在其他學者之曲線的右側，是因為本研究考慮了牆體臨界狀態之前的永久變位情況。三、加速度反應由增幅往減幅發展的過程與過往研究趨勢相近，並透過三種方法去討論放大因子運用。四、加勁牆體再受到地表作用下，最大變位在牆體中層，當牆前坡腳角度逐漸增大，最大變位位置逐漸從牆體中層往上層移動。五、運用Arias intensity 和 Rms method來表示地震波之能量比HPGA更能清楚表示強弱，當牆前坡腳角度越大，牆體破壞所需能量越小。

In present study,geosynthetic-reinforced walls were used to having a shaking table test.A laminar box was used to reduce boundary effect.About the test medium used in this study is a medium-dense river sand.Through various peak acceleration, frequency, length of reinforcement and angle difference in front of the wall were used in the model test to investigate their on the dynamic behavior of the geosynthetic-reinforced walls.Results of a comparative study between the test results reported in the literature and those in the present study reveal: 1. The seismic displacement are significantly affected by the frequency of base motion, i.e., seismic displacement increase with decreasing frequency of base motions, for identical values of horizontal peak ground acceleration(HPGA). 2. The normalized displacement curves obtained here fall to the right of analytical and empirical curves reported in the literature, suggesting that a permanent displacement of the slope prior to the yielding of the slope occurs. This phenomenon has not been considered in previous studies. 3. Transitions from an amplification state to a de-amplification state occur at certain levels of input ground accelerations, depending on the input wave motion. 4. Through multiple methods to represent the amplification factor, such as Max. of peak acceleration, Rms method and Arias intensity.These methods shows the similar trend about amplification and de-amplification,but each of them have the different transition point. 5. Through change the slope angel in front of the wall, the maximum lateral displacement position change from middle of the wall to top of the wall.
