摘　　要：通过对四川省境内线多条500k V超高压输电线路地质灾害和隐患的调查评估,分析了输电线路地质灾害的主要特点及其与所处区域的关系,并以黄达线157号塔和九石线36号塔为例,分析地质灾害的类型和危害方式及相应的减灾措施。得到以下结论 :输电线路地质灾害类型多,规模小,发生频率高,受地形地貌影响明显;线路地质灾害与区域地质灾害分布高度吻合,具有典型的区域分布特点;输电线路地质灾害治理措施需分清原理,因地制宜。Based on the investigation and evaluation on geological hazard and hidden trouble of 500kV extremely high voltage transmission lines in Sichuan province, the main characteristic of geological hazards and its relationship with the located area were analyzed. By given two examples, such as the No. 157 pylon in transmission line of Huangyan to Dazhou and the No. 36 pylon in transmission line of Jiulong to Shimian, the type and harm mode of geological hazard and corresponding mitigation measures were analyzed and presented. The results showed that：the geological hazards of transmission line have the characteristics of various types, small scale and high frequency. Topography and geomorphology have significant influence on the geological hazards of transmission line, which highly inosculated with the distribution of regional geological disasters, and they also have the characteristics of typical regional distribution. Control measures of geological hazard need to distinguish principle, and adjust measures to local conditions.
