摘要:
针对某上游式高尾矿坝，采用经验类推方法概化了尾矿坝沉积地层分布。根据经验及相关勘察报告估计了尾矿坝不同分区渗透系数，采用二维及三维有限元方法计算了尾矿坝在汛期和正常运行期不同干滩长度条件下渗流场分布，分别对堆积坝分段变坡及初期坝外甩尾碎石所形成的大型反压平台对渗流场及抗滑稳定的影响做了评估，给出了尾矿坝在不同工况下的渗透稳定性评估结果及抗滑稳定安全系数，为尾矿坝设计提供了依据。
Abstract:
Aiming at a certain upstream tailings dam, a recurrence method was used to estimate the deposited strata of the tailings dam. The permeability coefficients of different areas were obtained by the experience and related site investigation report. The seepage field in case of different beach lengths in flood or non flood period were simulated by 2D and 3D FEM. The computation also evaluated the affection to the seepage and stability by the different slopes in the embankment and a big rockfilled dam outside of the starter dam. At last, the seepage stability evaluation result and safety factors for stability analysis were presented, which provided an important reference for the tailings dam design.
