摘　　要：针对高压架空输电线路工程地基基础不连续的地质特点,总结了滑坡对线路工程的危害,根据岩质斜坡和土质斜坡的变形破坏模式,分析得出岩质斜坡滑坡和土质滑坡边缘至杆塔基础底面外边缘的水平距离的公式,并将分析方法应用到实际工程中,证明了高压架空输电线路工程中采用杆塔基础底面外边缘线至滑坡后缘水平距离来评价滑坡的影响是可行且有效的。According to the geologic characteristics of not continuous foundation of high voltage overhead transmission line engineering, this pa- per summarized the harms of landslide to line engineering, according to the deformation and failure modes of rock slope and soil slope, analyzed and gained the horizontal distance formula of rock slope landslide and soil landslide edge to pole tower foundation bottom surface outer edge, and applied the analysis method to practical engineering, proved using pole tower foundation bottom surface outer edge to landslide bottom edge line horizontal distance in high voltage overhead transmission line engineering to evaluate the landslide influence was feasible and effective.
