INCREMENT POISSONS RATIO FOR FROZEN CLAY WITH THERMAL GRADIENT

摘要：

The increment Poissons ratio for frozen clay with thermal gradient both in K0DCGF (K0 drained consolidation,freezing with non-uniform temperature under loading) and GFC (freezing with non-uniform temperature,isotropic consolidation) triaxial compression tests were investigated.The results indicated that the increment Poissons ratio decreases with the increasing in axial strain at various consolidation pressures and thermal gradients,but that increases both in K0DCGF test and GFC test with the further increasing in axial strain.The μinc,i(initial increment Poissons ratio)and the μinc,f(failure increment Poissons ratio) increase as the thermal gradient increased both in K0DCGF test and GFC test.However,the effects of consolidation pressure to μinc,i and the μinc,f present the inverse law in K0DCGF test and GFC test.
