摘要
利用非饱和土渗流理论,对沟后混凝土面板砂砾石坝进行瞬态渗流数值模拟。通过对均质坝体和坝料明显分层后坝体的渗流场进行对比分析,研究了两种情况下坝体渗流场随时间的变化特性以及水力参数的分布特性。指出填料严重分层后对坝体渗流场的影响以及对坝坡渗透稳定性的不利影响。
Transient seepage analyses for Gouhou concrete faced rockfill dam were conducted using the unsaturated soil seepage theory. Through comparison of the seepage fields in a uniform dam and an evidently stratified dam, the evolution of seepage with time and the distribution characteristics of the hydraulic parameters in the two cases were studied. The effects of the stratification of rockfill on the seepage field and the stability of the dam slope were highlighted.
