【摘要】 排土场是矿山剥离的松散堆积体,其中的渗流运动较为复杂,实际工程中很难以一般的公式来判别其中的渗流状态。以非线性渗流的普遍表达式建立排土场渗流数学模型,针对排土场渗流特点编制了有限元法计算程序。计算结果表明,排土场渗流区普遍存在非线性渗流状态,计算出的非线性渗流水位较线性渗流水位高。以该方法进行排土场渗流数值计算,根据数值分析结果进行排土场渗流状态的判别,并以之作为排土场稳定性分析的渗流参数,更符合实际,而且偏于安全。更多还原

【Abstract】 The seepage in waste dump of mine is complicated. Based on the nonlinear seepage formula,a numerical model of seepage in waste dump is established. A case study shows that nonlinear seepage exists in all the seepage area of the waste dump and the water level is higher than that of linear seepage. Therefore,the seepage computation using nonlinear seepage model is suitable and safe for mine waste dump.更多还原
