中文摘要:针对复杂地形条件下废石中线法尾矿坝的特点,采用饱和-非饱和三维有限元渗流分析方法,对尾矿坝三维渗流场进行数值模拟,分析了渗流场的分布规律,研究表明:复杂地形条件下,尾矿坝渗流场具有明显的三维分布特征,废石中线法尾矿坝具有浸润线低、渗透稳定性好等特点,对坝体抗震稳定性有利。研究成果可为类似工程的研究及设计提供参考。

3D seepage characteristics analysis for tailings dam by using centerline embankment method with waste rock
Abstract:Bast on a tailings dam by using centerline embankment method with waste rock under complex terrain condition, the saturation-unsaturation infiltration field of tailings dam were calculated with 3D finite element method, and the distribution rule of seepage field were analysed. The research showed that the seepage field of tailings dam under complex terrain condition changed with three dimensional characteristics, tailings dam by using centerline embankment method with waste rock have different characteristics of low water level and high permeability, which is advantageous to its aseismic stability. the result can provide reference for similar engineering research and design.
