In recent years,highway,especially expressway is under rapid construction throughout the world.The Infl uence of moisture content on coupling mechanical properties of plant fi ber-rope slope soil interface was studied by using self-made tensile equipment through mechanical experiments on plant fi berreinforced&slope soil.The study mainly involved 2 groups of experiments,the mechanical properties of slope soil with structural damages were experimented in the experiments of Group I;the mechanical properties of slope soil with structural retention were experimented in the experiments of Group II.The results showed that coupling mechanical properties between the plant fi ber and slope soil in the experiments of Group I were signifi cantly infl uenced by the moisture content,and the tensile strength of the plant fi ber decreased linearly with the increase in the moisture content,the infl uence of the moisture content on the friction angle was insignifi cant,and the cohesive force decreased exponentially with the increase in the moisture content.The coupling mechanical properties of plant fi ber and slope soil in the experiments of Group II were also signifi cantly infl uenced by the moisture content,and the peak strength and residual strength of the plant fi ber and slope soil decreased exponentially with the increase in the moisture content. 展开更多
