摘要
用有限元法对某水电站坝址区的渗流场参数进行了反演,结合工程地质和水文地质资料以及坝区的钻孔抽注水试验,反演得到了各覆盖层的渗透系数,并计算了整个坝址区的渗流场,为大坝建成后运营期的渗流场计算提供了基础。
According to the engineering geology and the hydrogeology of a certain hydropower station, a finite element model with 8 geological layers and complicated boundary condition is built. The experimental results of drilling test, the pumping well test and the injection test are collected and selected as the reference points in the process of inverse analysis. The inverse analysis result shows that it is in good agreement with the experimental result at the reference points. The permeability coefficients for each geological layer and region are obtained; and the seepage field of the whole foundation of the dam has also been calculated. All of these provide the fundamental parameters for the design of dam or further analysis to check the rationality of the engineering design.
