摘　　要：针对某山谷型尾矿库渗流场问题,基于矿库实测地形图与岩土地层勘察资料,依据地形概化的方法,采用MIDAS/GTS软件自带的地形生成器导入实际地形,建立反映尾矿库地形、地质结构特征的三维数值计算模型。运用GTS渗流分析模块进行尾矿库三维渗流场模拟计算,得到尾矿库浸润线的空间分布位置。结果表明,山谷型尾矿库几何体型受到山谷复杂地形的控制,边界形状复杂,渗流场分布相对紊乱;GTS渗流分析结果符合实际规律,可以作为工程的参考依据。Aiming at the problem of seepage field of a valley tailings reservoir,based on the measured topographic map of the reservoir and the survey data of rock and soil strata,according to the method of ter rain generalization,the terrain generator of MIDAS/GTS software is used to import the actual terrain,and a three-dimensional numerical calculation model reflecting the terrain and geological structure characteristics of the tailings reservoir is established.The GTS seepage analysis module is used to simulate the three-di mensional seepage field of the tailings reservoir,and the spatial distribution position of the tailings reservoir saturation line is obtained.The results show that the geometric shape of the valley tailings reservoir is con trolled by the complex terrain of the valley,the boundary shape is complex,and the distribution of the seep age field is relatively disordered.The results of GTS seepage analysis are in line with the actual law and can be used as a reference for engineering.
