摘要
针对江口水电站坝址区地质条件 ,在水平和垂直方向同时进行了渗透性分区 ;采用三维有限元法 ,并考虑了岩体各向异性的特点和降雨入渗补给边界 ,对坝址区渗流场进行了计算分析。该计算模型能真实反映实际情况。通过计算 ,论证了现有防渗帷幕和排水设计方案的明显渗控效果 。
In order to simulate truly the underground water seeppage of Jiangkou Hydroelectric Station's dam area, the three dimensional seepage model was founded by 3 D FEM under the conditions of the features of terrane anisotropism and supplementary boundaries of rainfall infiltration. The dam area is separated into several zones according to penetrability in horizontal and vertical directions. A series of models is considered. The results of these models show that the seepage control of proof curtain and draining system is efficient, and the data may be used as the basis for design.
