摘要
在稳定性分析过程中,尾矿库力学参数选取困难,尾矿库边界条件复杂,需要能够较为精确预测尾矿坝浸润线位置和稳定性计算的方法。在饱和-非饱和渗流理论研究的基础上,对尾矿库渗流场的分布进行了数值模拟,通过对比研究,饱和-非饱和模型比饱和渗流模型更加符合尾矿库的渗流规律。研究了初期坝透水性与干滩长度对尾矿库浸润线的影响,对比分析了影响尾矿库渗流的一些关键因素,以期能更好地解决尾矿库渗流稳定性评估问题。
In the stability analysis of the tailings, the selection of the mechanical parameters of the tailings is usually inaccurate and so it is badly in need of a more accurate method to forecast tailings dam seepage line location and stability calculation because of the boundary conditions of the tailings. Based on the saturated-unsaturated seepage theory, the distribution of the tailing pond seepage field is simulated in this paper. Through comparative study, it is found that saturated-unsaturated model can better agree to the tailings seepage rule than saturated seepage model; the influences of the initial dam permeability and dry length on the tailings infiltrating line are researched. The paper has also analyzed some key factors a-f fecting the tailings seepage in order to better address the tailings seepage stability assessment.
