Title: | A bounding surface model for saturated and unsaturated soil-structure interfaces | Authors: | Zhou, C Tai, P Yin, JH |
Issue Date: | Dec-2020 | Source: | International journal for numerical and analytical methods in geomechanics, Dec. 2020, v. 44, no. 18, p. 2412-2429 | Abstract: | In many geotechnical systems, such as reinforced slopes and embankments, soil-structure interfaces are often unsaturated. Shear behaviour of unsaturated interfaces is strongly dependent on their matric suctions, as revealed by the results of extensive laboratory tests. So far, constitutive models for unsaturated interfaces are very limited in the literature. This paper reports a new bounding surface model for saturated and unsaturated interfaces. New formulations were developed to incorporate suction effects on the flow rule and plastic modulus. To examine the capability of the proposed model, it was applied to simulate suction- and stress-controlled direct shear tests on unsaturated soil–cement, soil–steel and soil–geotextile interfaces. Measured and computed results are well matched, demonstrating that the proposed model can well capture key features of the shear behaviour of unsaturated interfaces, including suction-dependent dilatancy, stress–strain relation and peak and critical state shear strengths. | Keywords: | Critical state Dilatancy Soil-structure interface Suction Unsaturated |
