Slope displacement and soil pressure of soilbag-retaining wall influenced by arrangement Available to Purchase

Soilbags have a good effect on slope reinforcement. In this paper, five kinds of physical model tests were carried out on slopes strengthened by reinforced soilbag-retaining wall, namely analysis of the failure mode and failure pressure of the slope, the variation trend of horizontal displacement of the slope, the maximum horizontal displacement and the horizontal transmission and vertical distribution of earth pressure. Thus, the influence of the arrangement mode of the soilbags on the slope reinforcement effect were studied. The results show that the alternate arrangement between layers (arrangement mode 1) had the deepest slip surface, the maximum bearing capacity and the minimum horizontal displacement, thus its reinforcement effect was the best. In addition, the reinforcement effect of the slope was related to the amount of tail embedded into the slope body, the interaction of soilbags in the layer and the embedment between the upper and the lower layers of soilbags. It was found that when the embedding degree of the tails into the slope was higher, the horizontal deformation constraint of the slope was stronger, resulting in a deeper sliding surface and a higher ultimate bearing capacity of the slope. This shows that the slope reinforcement effect was better with soilbags.
