“…The bending moment in the pile is positive above the inflection point (bending in the same direction as soil sliding), while it is negative below the inflection point (bending in the opposite direction to soil sliding). This bending moment behavior resembles that of a micro-pile reinforced earth retaining wall [18,19,22]. With an increasing load, the positions of the maximum bending moment and the inflection point remain relatively constant, but the magnitude of the bending moment increases significantly, reaching a peak of 115.88 N•m.…”

Reinforcement soil slope with pile penetration is a new load bearing structure, which has a complex working mechanism, but few studies have been carried out. This paper aims to investigate the stability characteristics of this structure using model tests. The study investigates the lateral displacement and-pile bending moment caused by vertical loads and evaluates the influence of different factors, including the structure type (such as pile, cap of pile, and reinforcement material), number of reinforcing layers, spacing of reinforcement material, pile length, and slope rate on the load-carrying capacity of the pile penetration fill-reinforced load-bearing structure. The findings suggest that within a certain range, increasing the pile length and number of reinforcing layers, the limiting effect of the pile on the lateral displacement in the middle and at the bottom of the slope of the pile-penetrating reinforced structure is enhanced, which can reduce the extreme value of the bending moment and make the distribution of the bending moment of the pile more reasonable. The lateral limiting effect on the soil body can be maximized by appropriate reinforcement spacing. Within a certain range, the slope rate is reduced, which can reduce the extreme value of the bending moment, make the bending moment distribution of the pile more reasonable, and avoid the phenomenon of the localized force concentration of the pile.

“…Therefore, plain knitted cotton fabric was used as reinforcement in the test, and the thickness was about 0.2 mm. According to the literature [18,19], the material properties of plain knitted cotton fabric were studied. The material parameters of plain knitted cotton fabric are shown in Table 2.…”
