Effect of Consolidation Time on Dynamic Shear Modulus of Soft Clay

摘要：

The hardened effect that represents the soft clay harden gradually with the increment of consolidation time, makes dynamic shear modulus of soft clay increased; meanwhile, the size effect that represents the height and diameter of the sample decreased gradually, also produces effects on dynamic shear modulus of soft clay. A serial of free vibration column tests of soft clay was conducted to analyze the effects of consolidation time on maximal dynamic shear modulus, dynamic shear modulus ratio and samples size of soft clay. According to the basic principle of the free vibration column test, the effects of varied size of sample on dynamic shear modulus of soft clay are analyzed. Combined with the relationships between consolidation time and samples size obtained from the tests, the size effects of consolidation time on maximum dynamic shear modulus of soft clay are analyzed.
