The description of the deformation behavior of Shirasu (volcanic sandy soil) by the elastoplastic constitutive equation is studied adopting a subloading surface model with rotational hardening. Also, test results for isotropic consolidation and triaxial compression with several lateral stresses under the drained and the undrained conditions for various initial void ratios are reported. Further, simulation by the constitutive equation is compared with the test results. High ability of the constitutive equation for the prediction of mechanical behavior of Shirasu is verified by the comparison.
