| In this study、banking and seepage analyses were carried out with various combinations of the core and the filter widths in order to evaluate safety of earth core zone、which has the function of imperviousness of dam body、based on hydraulic fracturing. Based on the laboratory tests of hydraulic fracturing of core materials for rockfill dams and the safety evaluation against hydraulic fracturing of earth core useing banking and seepage analyses、we finally proposed rational design method of earth core width. |
