摘要
通过对湖南某尾矿坝细粒尾砂的常水头渗透试验,进行了细粒尾砂孔隙比与渗透系数常用对数的拟合分析,建立了二者之间的数学表达式,对不同孔隙比的细粒尾砂尾矿坝进行了渗流数值模拟分析,得出孔隙比与尾矿坝浸润线埋深之间的关系,提出了该尾矿坝在渗流作用下安全运行的最优孔隙比范围。
Taking a tailings dam in Hunan province as the study example,the constant heat permeability test of fine grained milltailings is conducted,and fitting analysis between void ratio of fine grained milltailings and common logarithm of permeability coefficient is done,the numerical simulation seepage analysis of the tailings dam with fine grained milltailings with different void ratio is done,the relationship between void ratio and the saturation line depth of tailings dam is analyzed,besides that,the optimal scope of void ratio of the tialing dam under the action of seepage is obtained.
