Effect of Particle

In order to investigate the influence of sand particle-size gradation on cyclic and postcyclic shear strength behaviour on sand-geotextile interfaces a series of monotonic direct shear (MDS) cyclic direct shear (CDS) and postcyclic direct shear (PCDS) tests were performed using a large-scale direct shear apparatus The influence of cyclic shear history on the direct shear behaviour of the
