基于GEO-Studio对尾矿坝渗流数值模拟计算分析

Numerical simulation and analysis of tailings dam seepage based on GEO-Studio

该文采用GEO-Studio计算软件建立尾矿坝二维有限元计算模型对尾矿坝进行渗流场计算,计算浸润线埋深与实测浸润线埋深进行对比分析得到采用GEO-Studio计算软件对尾矿坝进行渗流计算的合理性;并对后期尾矿坝加高后渗流进行数值计算,可预测后期尾矿坝渗流规律,为企业安全管理尾矿坝,控制库内水位及干滩长度提供重要参考依据,以确保尾矿坝的安全稳定运行。

In this paper,a two-dimensional finite element calculation model of tailings dam was established by GEO-Studio software to calculate the seepage field of tailings dam.Then the calculated seepage line depth was compared with the measurement results,to analyze the rationality of using GEO-Studio for calculating tailings dam seepage.After a higher tailings dam was taken,numerical calculation was performed again for the new seepage flow.This model can be used to predict the subsequent seepage patterns.This model provides a significant reference for enterprises to manage the safety of tailings dams,control the reservoir water level,and maintain the beach length,so as to ensure safe and stable operation of tailings dams.
