| Abstract: | According to the layout,condition of thick and complex riverbed overburden of Shaping hydroelectric project headwork,formulated many kinds of scheme by different depth of concrete impermeable wall,through analysis of 3D seepage flow finite element method,seepage quantity and gradient of permeation calculation,sensitivity analyses and floating value analyses to coefficient of permeability of riverbed overburden,appraise the effect of impervious measure of gate dam base for ever scheme and Optimize the depth of concrete impermeable wall.The result provides the foundation for the optimization design. |
