摘要: |
利用渗流微分方程及模型试验提供的溢流边界条件,通过有限差分法求解堆石体渗流场等势线的数值及渗流量。根据渗流动力方程及试验确定的阻力系数拟合方程,导出了堆石体内各流区运用的非线性渗流浸润线计算式。实例计算值与试验结果吻合。 |

Abstract: |
In this paper, the field and discharge of seepage of overtopping rock fill are calculated by using the numerical method and eyperimental boundary. And the calculation formula of nonlinear infiltration line are reasoned by using seepage motive formula and experimental seepage resistance factor. The results are in good agreement with experiment. |
Key words: overtopping rockfill,seepage field,seepage discharge, infiltration line |
