摘要
采用有限元对复杂地形的尾矿库渗流场进行数值模拟分析时,提出了三维数值模型概化的新方法:将地形剖面上的主要控制点拟合成曲线,然后再将曲线拟合成曲面,最后由曲面生成概化的三维数值模型。在此基础上进行了某尾矿库的三维渗流场计算,计算结果与该尾矿库的实测资料吻合良好,表明了模型概化的合理性。
This paper puts forth a generalization method of 3-D numerical model for finite element analysis of 3-D seepage flow field in the tailing pond of a complex terrain.In this generalization,fitting curves are generated to the data of major control points of topographical profiles,and a curved surface is created from these curves.Then using the curved surfaces a 3-D generalization model can be built.By this method,the 3-D seepage flow was simulated and the results are in good agreement with the measurements.
