Abstract: The mecanism of hydraulic fracturing in the core-type rockfill dams was studied in this paper. Series of laboratory seepage fracture tests were carried out on fill materials to investigate the relationship between the hydraulic gradient at failure and the state of effective confining pressures. FE stress analysis was made on a typical model rockfill dam, to examine the process of stress redistribution in the core zone due to wetting and the local stress states to be compared with hydraulic conditions. These results were summarized to propose a practically useful procedure of evaluating the posibility of hydraulic fracturing in rockfill dams.
