滑坡对输电线路的危害及防治措施

Landslide Hazard to Transmission Line and Its Prevention and Treatment Measures

摘要:

滑坡是输电线路最常见的灾害之一，具有严重的危害性。文中针对滑坡对输电线路的危害以及防治措施进行了研究。首先，从自然因素和人为因素分析了输电线路滑坡诱因；然后，根据实际工程经验分别阐述了滑坡灾害对输电铁塔和基础不利影响的分析方法，并归纳总结了输电线路设计时预防滑坡灾害的工程措施；最后，分析了抗滑桩和桩板挡墙、锚杆（索）格构梁、重力式挡墙、微型桩等输电线路工程中几种常见滑坡治理方法的优劣，为输电线路滑坡灾害的预防和治理提供借鉴。

Abstract:

Landslide is one of the most common disasters in transmission lines and has serious harmfulness. In order to study the harm of landslides to transmission lines and its prevention and control measures, firstly the landslide inducing factors of transmission lines are analyzed, which are mainly divided into natural factors and human factors. Then according to the practical engineering experiences, the adverse effect of landslide disaster to transmission towers and foundations is described respectively, and the engineering measures in transmission line design to prevent landslide disaster are summarized. Finally, several common landslide treatment methods in transmission line engineering such as the anti-slide pile and pile retaining wall, anchor rod (rope) lattice beam, gravity retaining wall and micro pile etc, are introduced. The research results will provide experiences for the prevention and treatment of landslide disaster in transmission lines in the future.
