Abstract

Both theoretical analysis and laboratory test data indicate that for normally consolidated soft clays the coefficient of lateral earth pressure at rest, Ko, gradually increases with time. Physical reasonining suggests that for all soils Ko should asymptotically approach unity. This reasoning implies that for overconsolidated soils with initial values of Ko greater than one, Ko should decrease with time. The time dependence of Ko has significant implications with respect to how the value of Ko measured in laboratory tests relates to in-situ values of Ko.
