Abstract

As an important seismic resisting element, the dynamic response law of the lattice retaining wall is of great significance for its design and assessment of seismic performance. Therefore, a numerical computational model of the gabion retaining wall was established using particle flow software. The horizontal EI-Centro-NS seismic waves with different peaks were input to study the dynamic response of the gabion retaining wall under horizontal seismic loading. The results show that: the peak dynamic stress of the gabion retaining wall increases-decreases-increases with the height of the wall, and reaches the maximum at 5H/6, forming a dynamic stress amplification zone, and the total dynamic soil pressure is distributed as an “inverted triangle”; the horizontal displacement of the retaining wall and the vertical displacement of the retaining wall are both larger with the peak acceleration, reaching the maximum at the bottom of the wall, and both of them reach the maximum at the bottom. The horizontal and vertical displacements of the retaining wall both increase with the peak acceleration, reach the maximum value at the bottom, and gradually decrease along the height of the wall, and the vertical displacement is less affected. Under the excitation of four peaks of horizontal seismic wave, the retaining wall did not show obvious damage, and the flexibility of the grid retaining wall can absorb the seismic energy well, thus improving the seismic performance of the retaining wall.
