Post-Cyclic Drained Shear Behaviour of Fujian Sand under Various Loading Conditions

In offshore engineering, the sand beneath an embankment may be subjected to traffic loads, resulting in a series of engineering issues. The behaviour change under long-term load. A drained cyclic and post-cyclic monotonic triaxial tests were performed on Fujian with different relative densities. strength stress–dilatancy behaviours studied. results indicated that normalised peak ratio after loading was greater than without loading, depending stress amplitude, while critical state seemed only slightly affected by history. dilative response could also influenced loading-induced fabric. Under constant density conditions, higher amplitude applied sample, larger volume strain produced state. Furthermore, cyclic-induced fabric destroyed 6% axial strain.
