    Abstract:

    : A large-scale shaking table model test was carried out to study the effects of ground motion parameters on the cell strain and the acceleration of the retaining wall. The results show that the cell strain and acceleration change nonlinearly along the wall height. With the increase of amplitude and frequency, the cell strain and acceleration increase gradually, and the maximum strain appears near the elevation 11/2. The increase of cell strain and acceleration is small when the frequency is 1~4Hz, and larger when the frequency is more than 4Hz. Under the three directions, the dynamic response of the retaining wall is the strongest when the action is in the XZ direction. While the time of persistence has little effect. The acceleration of column 1 is less than that of column 2, and the retaining wall of the geocellular cell has a certain attenuation effect on the seismic energy, showing good seismic performance. The research results have certain reference value for seismic design and practical application of geocell retaining wall.
