本文以柿竹园野鸡尾尾矿库为依托,采用有限元方法对其渗流及稳定性进行分析。利用热流与地下水渗流有限元实现环境的相似性,模拟尾矿库的渗流场并进行分析,确定渗流浸润线及水头分布情况;对浸润线上下的土体采用不同的容重,并考虑有效应力参数,建立有限元静力分析模型,并分别从应力、滑移面、塑性区等方面对尾矿库的静力稳定性做了简要分析,同时研究探讨库区水位变化对尾矿库稳定性的影响。结果表明:在给定的计算条件下,野鸡尾尾矿库在渗流下的稳定性良好,具有较高的安全储备,库区水位变化对于该尾矿库稳定性的影响并不大。

Based on Yejiwei Tailing Pond in Shizhuyuan, the seepage and stability are analyzed using the finite element method (FEM). Using finite element of heat flow and groundwater seepage to achieve environmental similarity, the seepage field of the tailing pond was simulated and analyzed, its saturation line and waterhead distribution were defined. The finite element model was set up for static analysis by using different volume weights for the soil up and down the saturation line with considering of the effective stress parameters, and the static stability of the tailing pond was analyzed from stress, slip surface and plastic zone. At the same time, the effect to the stability of the tailing pond caused by the changing water level was discussed. The results show that the stability of this tailing pond is well under seepage condition and the changing water level do little effect on its stability.
