| 摘 要： | 基于有限元数值计算结果,分别讨论了均质土坝和各向异性土坝多个位置坝基防渗帷幕对浸润线和渗流量的影响,阐述了浸润线和渗流量变化的一般趋势,得出了均质土坝最有利的坝基防渗体位置位于坝轴线或坝轴线上游附近坝基中的结论,但随着kx/ky的增大,坝基防渗体的防渗作用将逐渐减小。

| Abstract: | Based on the numerical results got by finite element method,the influences of multiple locations of impervious curtain on the saturation line and seepage are discussed.The general tendency of saturation line and seepage change is elaborated,and the conclusion that the most favorable location of impervious body of homogeneous dam foundation is on the dam axis and the upper part of dam axis is drawn,however,with the increase of kx/ky,the impervious effect of the impervious body of dam foundation will decrease... |
