Abstract：Geotextiles are extensively employed for slope reinforcement in granite residual soil regions. However, the static and dynamic shear characteristics of geotextile-granite residual soil interfaces under wet-dry conditions remain inadequately understood. This study conducted monotonic and cyclic shear tests on the interface between geotextile and granite residual soil, considering wet-dry effects. The shear stress-displacement relationships, shear strength parameters, and shear stiffness variations were analyzed with respect to wet-dry cycles and amplitudes. The results indicate that during monotonic shear processes, interface roughness progressively increases with wet-dry cycles. The wet-dry cycle has a more pronounced impact on the strength parameters of the geotextile-soil interface compared to the wet-dry amplitude. With the increasing number of shear cycles, the hysteresis curve of the geotextile-soil interface expands outward, and the interface shear stiffness increases, while the damping ratio decreases. Cyclic shear cycles have a limited effect on strength parameters, whereas wet-dry cycles primarily influence the cyclic shear modulus. Cohesion is more significantly affected by cyclic shear history than the internal friction angle. Additionally, repeated wet-dry processes weaken the structural integrity of granite residual soil and enhance the interlocking action of the geotextile-soil interface. The cyclic shear process can reduce the roughness of the geotextile-soil interface, which explains the observed trend of initially increasing and subsequently decreasing interface shear characteristics under varying wet-dry histories.
