Samenvatting
Published methods of predicting in situ lateral stress from the dilatometer test are reviewed. A data base containing high-quality information from clay test bed sites mainly in norway and the united kingdom has been established. Reference k sub 0 values have been evaluated from a number of methods including self-boring pressuremeter, hydraulic fracture, total stress cells, laboratory measurements, and empirical correlations. A nw correlation between the dilatometer parameter k sub d and k sub 0 is proposed for young clays. This paper appears in transportation research record no. 1278, Dynamic testing of aggregates and soils and lateral stress measurements 1990.
