| Abstract: | Geo-Seep program,finite element analysis and saturated-nonsaturated transfusion theory were used for back analysis to determine permeability coefficient of materials in the main cross of the dam,and the calculation of operating parameters under the design water level,including phreatic line,seepage gradient,equi-potential line head and water pressure. Compared with the design allowable value,the paper evaluated the operation conditions of the dam. |
