| 摘 要： | 煤矿采空区的塌陷与变形对高压供电线塔基的稳定构成了极大的威胁．使用高密度电法对塔基附近的地质结构进行了探测，应用二维和准三维反演方法确定了地下电阻率分布形态，以此为基础推断解释了塔基附近煤矿采空区的位置和形态，并对塔基的加固处理提出了建议。

| Abstract: | The sinking and deformation occurred in coal mined area do seriously effect the stability and safety on high power tower. High Density Electricity Method is used to survey engineering geology nearby the tower. 2-D and 3-D inversion methods are employed to determine the distribution of the resistivity, and the location and side of the mined cavity can be explained through the underground resistivity distribution. Some proposes are raised to reinforce the foundation of the tower. |
