AB  - Characterisation of shearing behaviour at soil-structure interfaces is critical in the analysis and design of a wide range of geotechnical structures. Large-displacement ring shear interface testing employing preshearing stages has been recognised as a robust approach for characterising interface resistance, particularly when large relative displacements are developed between soil and interface during either installation or operation. Such tests are applied in practical design approaches, for example in the ICP method for driven piles (Jardine et al., 2005). This paper presents a database of interface shearing tests involving sandy-silty soils that contain low percentage (≤ 20%) of non-plastic fines, integrating outcomes from research and project studies conducted at Imperial College London and the Norwegian Geotechnical Institute using Bishop Ring Shear apparatuses. The outcomes enable a critical review of the potential effects of a wide range of factors, including: soil physical index properties (grading, fines content); interface characteristics (material type, surface roughness); and applied testing conditions (shear rate and normal effective stress). Trends identified from the datasets are integrated with previously reported studies to indicate the interface shear strength parameters that may be adopted for preliminary design with non-plastic sandy-silty soils on the basis of simple index tests.
