Abstract
In order to investigate the rate effect on cyclic shear characteristics of clays with various plasticity, a series of undrained cyclic triaxial compression tests has been performed applying cyclic loads with various frequency. Firstly, the effect of frequency on the development of excess pore pressure and axial strain was investigated. Then the relation of axial strain against effective stress ratio was correlated by the cyclic load frequency.
As the major work of the present study, the cyclic shear strengths of clays with various plasticity were investigated and formulated in terms of plasticity index and load frequency. As a result it has become possible to evaluate the cyclic shear strengths of soils with various plasticity and initial stress condition subjected to various frequency of cyclic loads.
