| Abstract: | With the No.12 typical overflow dam section of the Guangzhao concrete gravity dam of 200m in height as an object for study, the main factors affecting the seepage field around the dam were analyzed by use of the method of nodal virtual flow rate, the techniques of drainage substructures and drainage hole switches, and the 3-D finite element method. Through comprehensive analysis of the characteristics of seepage through the dam body and dam foundation, an optimal scheme for seepage control of the dam foundation was proposed, and the reliability, rationality, and safety of the water head figure for the designed uplift were evaluated. Furthermore, some reasonable suggestions were put forward. |
