In this study, the time dependent characteristics of the soil pressure coefficient is theoretically investigated and a new model is developed to evaluate the static soil pressure in a normally consolidated soil deposit during geological era. The volumetric deformation of soil is described by the Kelvin model, while its shear deformation is represented by the modified Maxwell model assuming the shear- creep relationship as a linear function of the time logarithm. By employing the “elastic-viscoelastic correspondence principle”, the coefficient of soil pressure is found as a function of time, indicating an increase within the geological time span
