Shear Strength of Unsaturated Soil-Geotextile Interfaces
Geotextiles are widely used in various applications including earthen structures, which are often built in unsaturated soil conditions. The design of these earthen structures is often dominated by the shear strength of the interface between soil and reinforcement (i.e. geotextile) layers. However, the unsaturated soil-geotextile interface interactions are not completely understood. This paper examines the shearing behavior of unsaturated soil-geotextile interfaces. Direct shear test results are used to define failure envelopes for unsaturated soil and soil-goetextile interfaces. Experimental results reveal a nonlinear relationship between the soil-geotextile interface strength and matric suction. The paper demonstrates that this non-linear failure envelope can be modeled using the Soil Water Characteristic Curve (SWCC) and saturated effective stress-strength parameters. The paper also compares the shearing behavior of unsaturated soil and unsaturated soil-geotextile interfaces.
