Effect of Dry-Wet Cycles and Freeze-Thaw Cycles on the Antierosion Ability of Fiber-Reinforced Loess

Compared with plain soil, polypropylene (PP) fiber-reinforced soil has markedly improved mechanical properties and can be used in slope protection projects. To investigate the reduction law of antierosion ability parameters PP loess under dry-wet (D-W) cycles freeze-thaw (F-T) cycles, we took from Yan’an, China, mixed them fiber, did shear strength tests, disintegration permeability tests D-W F-T cycles. The experimental results show that or had a less deteriorating effect on cohesion, rate, coefficient samples than loess; however, their internal friction angle was more obvious. Under cohesion reinforced decreased as number increased, while rate increased increased. relation between accorded hyperbolic function fitting results. most obvious followed by angle, coefficient. also coefficient, angle. stronger but greater
