Abstract

Shear stiffness of soil is one of the most important geotechnical parameters for predicting ground movements and monotonic and cyclic responses of many earth structures. In this keynote, a newly developed temperature and suction controlled cyclic triaxle apparatus is introduced. Measured results of anisotropic shear modulus at very small strains, shear modulus degradation curve at small strains and resilient modulus under cyclic loads at various suctions and temperatures are analyzed and reported. Semi-empirical state-dependent equations for anisotropic shear modulus and resilient modulus of unsaturated soil are proposed.
