摘　　要：基于某采空区对坐落于其上的输电铁塔塔基稳定性影响的数值分析结果,定量分析受开采影响的地表移动变形在时间和空间上的分布规律,用来判别建筑物是否受开采影响和受开采影响的程度,作为受影响建筑物进行维修、加固、重建或采取地下开采措施的重要依据,所得的结果与常用计算方法所得结果基本一致。Based on numerically analyzed results of impacting from a coalmine gob area on electric power line tower foundation stability above, quantitatively analyzed temporal and spatial distribution pattern of surface movement and deformation caused by coal mining. The results are used to discriminate whether or not the buildings impacted by mining and impact extent, thus as an important basis for impacted buildings maintenance, reinforcement, reconstruction or underground mining improving measures. The numerical analyzed results are basically consistent with results from common computation methods.
