Abstract

In this note an empirical expression for the coefficient of earth pressure at-rest K0 in terms of the mobilized angle of internal friction in one-dimensional compression of normally consolidated soils is presented. It was obtained from published experimental data in a straightforward manner and without any assumptions. Although it is empirical, the equation has a better basis in terms of soil behaviour than the familiar Jaky’s equation and, for the full range of K0 values considered, it provides slightly better predictions than the Jaky and three other prediction equations.
