持续的强降雨使得架空线路的基础边坡发生大规模边坡溜坡事故,给线路运行带来安全隐患。采用框架锚杆加固、框架内挂网喷浆或植被防护、三维网植草、加强截排水等一系列综合措施对边坡进行加固处理,取得良好的加固效果。主要通过现场岩土锚杆的拉拔试验以验证框架锚杆设计参数的合理性,结果表明框架锚杆对山区架空线路的边坡加固具有良好的经济技术效果,值得进一步推广应用。
持續的彊降雨使得架空線路的基礎邊坡髮生大規模邊坡霤坡事故,給線路運行帶來安全隱患。採用框架錨桿加固、框架內掛網噴漿或植被防護、三維網植草、加彊截排水等一繫列綜閤措施對邊坡進行加固處理,取得良好的加固效果。主要通過現場巖土錨桿的拉拔試驗以驗證框架錨桿設計參數的閤理性,結果錶明框架錨桿對山區架空線路的邊坡加固具有良好的經濟技術效果,值得進一步推廣應用。

The surface soil of foundation slopes for overhead tansmission line happens to sliding down after long-time heavy rain,which would hazard the safe operation of line project.The comprehensive measures of framework anchor reinforcement,concrete spraying,grass platting in the three-dimentional grid,draining and so on are taken to make the slope protection,and receiving good effects.In this paper,the rationalization for the design parameter of framework anchor in the mountainous area is confirmed by the pullout experiments for field anchors.The results show that the framework anchor is effective in practice and good for popularization in the slope reinforcement of overhead lines.
