摘要
应用三维非稳定饱和—非饱和渗流有限元法建立冲久水库枢纽区的三维有限元模型,分析了枢纽区渗流场的特性并比较不同蓄水速度下坝体的非稳定渗流特性,推荐了初次蓄水速度的控制值。
Three-dimensional finite element model of Chongjiu reservoir is built by using of saturated-unsaturated unsteady seepage 3-d FEM. By calculating for three different velocities, which are 0.5m/d, 1.0m/d, 2.0m/d, the characteristics of unsteady seepage flow of dam are compared. The control value of initial impounding velocity is proposed.
