Based on large-scale triaxial tests of sandy gravel materials, the strength and deformation characteristics under loading/unloading conditions are analyzed. At same time, applicability hyperbolic constitutive model to is studied using experimental data. The results indicate that low confining pressures (0.2 0.4 MPa) shows a weak softening trend; higher pressure, more obvious hardening tendency ...

This study was aimed at highlighting the effect of loading frequency on sand liquefaction response by performing cyclic triaxial tests in both stress-controlled and strain-controlled modes. For first case, dense (IDmat = 0.70) medium-dense 0.55) specimens were subjected to alternative non-alternative axial stresses; whilst strain over a wide range frequencies second case. It experimentally foun...
