[V-73] Stress dependency evaluation of shear modulus of soils by cyclic triaxial test combined with bender element test
Keywords:Subgrade, Shear modulus, Stress dependency, Bender element test, Cyclic triaxial test
In pavement design based on the theoretical design method, functional pavement design can be performed with a limited budget if the deformation modulus of the subgrade can be accurately understood. In this study, experiments were conducted on Toyoura sand and two alluvial clays with different soil properties using "cyclic triaxial test combined with bender element test (CTX-BE)". As a result of experiments and examinations, it was found that the shear modulus G and the mean effective stress p' have a unique correlation with each other for Toyoura sand and two alluvial clays.
