THE EMPIRICAL EVALUATION OF THE COEFFICIENT K0 AND K0R

摘要

References(11) Cited-By(1) The coefficient of lateral earth pressure at rest is obviously important in numerous engineering problems.Its value appears to be governed by the soil strength and the degree of overconsolidation. It is possible to determine the coefficient in the laboratory but, in order to establish its dependence on stress history, the procedure would be quite time-consuming-particularly in view of the elaborate equipment required.The problem is analyzed in this paper and empirical correlations, using index properties, are applied to suggest a reasonably reliable procedure to estimate the value of K0 for primary compression and unloading conditions.
