A Unified Description of Toyoura Sand
In this paper,the mechanical behavior of sand,was systematically described and modeled.Without losing the generality of the sand,a specific sand called as Toyoura sand,a typical clean sand found in Japan,has been discussed in detail.In the model,the results of conventional triaxial tests of the sand under different loading and drainage conditions were simulated with a fixed set of material parameters.The model only employs eight parameters among which five parameters are the same as those used in Cam-clay model.Once the parameters are determined with the conventional drained triaxial compression tests and undrained triaxial cyclic loading tests,and then they are fixed to uniquely describe the overall mechanical behaviors of the Toyoura sand,without changing the values of the eight parameters irrespective of what kind of the loadings or the drainage conditions may be.The capability of the model is discussed in a theoretical way.
