摘要
金川水电站坝址区覆盖层深厚,两岸边坡卸荷发育,考虑运用三维渗流有限元理论及3D-seep软件,结合两岸岩体绕渗,对竖向防渗深度进行对比研究,并对围堰及防渗体的渗透参数进行了敏感性分析,最后给出推荐的围堰防渗方案。
The overburden in the dam site area of Jinchuan Hydropower Project is deep and thick.The unloading of both banks is devel-oped.By application of 3D seepage finite element theory and 3D-seep software as well as in combination of bypass seepage of the rock-mass of both banks, the vertical impervious depth is compared and studied.Meanwhile , the sensitivity analysis on the permeable parame-ters of the cofferdam and impervious body are performed.Finally, the impervious scheme foe the cofferdam is proposed.
