the geogrid striped-reinforced method is proposed to improve its seismic performances. According to the soil-structure dynamic similarity system
a shaking table test model of the geogrid striped-reinforced waste tire-faced retaining wall is designed. This test model can consider the influence of seismic intensity
seismic wave
length of geogrid reinforcement
spacing of geogrid reinforcement and the slope of the wall. The seismic response characteristics were analyzed
such as the tire-faced wall and the backfill acceleration
the lateral displacement of the wall
the settlement of the backfill on the top of the wall and the dynamic soil pressure on the back of the wall. In addition
the characteristics are compared with those of the shaking table test of the waste tire-faced retaining wall (unreinforced). The results show that geogrid striped-reinforced tire-faced retaining walls significantly improve the seismic response characteristics of unreinforced retaining walls
and improve the seismic performance of the tread retaining wall. Thus
the geogrid striped-reinforced vertical waste tire-faced retaining wall can be used as an ideal wall for engineering application.
