摘　　要：为了研究铁矿未来采空区对高压线路塔基变形影响,采用FLAC3D软件,对铁矿充填开采过程进行了数值模拟,结果表明:因地下开采引起的最大地表位移在矿体两端移动范围边界附近,地表水平变形趋势为两侧向中间移动,在矿体两端移动范围内呈现对称分布,整个开采过程发生的向左、向右水平位移最大值均在20 mm左右,对塔基变形及位移影响甚微。In order to study the impact of future iron mine mined out area upon high-voltage line tower foundation deformation, the paper applies FLAC^3D software, and carries out numerical simulation for the mine mining process. Results show that： maximum ground surface displacement owning to underground mining is within the mine body lateral moving area; surface horizontal displacement trend is from the lateral side to the middle, which is symmetrical distribution within lateral mine moving scope; the maximum value of the left and the right horizontal displacement of the whole mining process is about 20 mm, which has little influence upon the tower foundation deformation and displacement.
