SOIL/NAIL INTERACTION MECHANISMS FROM LARGE DIRECT SHEAR TESTS

Soil nail interaction mechanisms have been investigated at University of Wales, Cardiff using the World's largest variable confining pressure direct shear box, under an EPSRC-funded contract. Research has focused on the effects of varying both nail stiffness and soil stiffness. Steel and aluminium nails 2.8m long and 25 mm diameter have been tested, in a medium dense sand under confining pressures of 100 kPa and 200 kPa and a compacted cohesive fill. Repeat testing was carried out so that at least two tests were carried out for each combination of nail type and soil type, the tests gave consistent results allowing a greater understanding of the development of forces in soil nails and providing a basis for the prediction of displacements which occur in soil nailed structures.
