dc.description.abstractThe purpose of this study is to present guidelines and correlations to estimate the coefficient of earth pressure at rest (K0) in Norwegian clays in absence of site-specific data. A database of K0-measurements from advanced laboratory tests and in situ tests was established. From a series of multivariate regression analyses, it was possible to develop empirical correlations between K0, overconsolidation ratio (OCR) and plasticity index (IP). The results of the statistical analyses showed high regression coefficients (i.e. R2>0.99) and suggest that the plasticity index, has little influence on K0, at least for Norwegian clays. Compared to the recommended relationships in this study, the well-known K0 chart from Brooker and Ireland (1965) shows greater variability about the correlation curves and seem to provide less reliable estimate of K0.nb_NO
