Abstract: Using large-scale shearing device, K0 consolidation-drained triaxial test and isotropic consolidation-drained triaxial test under different confining pressures are performed for three relative densities (0.9, 0.8, 0.7) overburden material of ShuangJiangKou earth dam. The difference between dilatancy behaviours of coarse-grained soil under K0-consolidation and isotropic consolidation is investigated. Meanwhile, applicability of the modified Rowe dilatancy equation for coarse-grained soils under K0-consolidation is tested. The test results show that the dilatancy under K0-consolidation is more remarkable than that under isotropic consolidation; and this difference is more obvious for coarse-grained soils with lower density. By means of the nonlinear fitting of the results of triaxial tests, a relationship formula for coarse-grained soils under K0-consolidation and isotropic consolidation among dilatancy factor and relative density and confining pressure is obtained, according to which, the dilatancy' strength of coarse-grained soil under different consolidations can be judged. For the coarse-grained materials under K0-consolidation, of which dilatancy characteristics can be reflected well by the modified Rowe dilatancy equation.
