浅析输电线路基础边坡保护距离

在输电线路竣工验收过程中,经常发现塔基的边坡保护距离a值不够,文章分析了造成边坡保护距离a值不够的原因有施工方不严格按图施工、测量错误、设计原因。针对该问题,最有效的办法是设计人员在配置陡峭地形的基础时,采用掏挖基础或人工挖孔桩基础,并加大基础埋深。在问题出现后,采用补救措施,采用挡土墙或浆砌石回填。不管采用哪种措施,都是为了保证输电线路运行的稳定性和安全性。

A Brief Analysis on Slope Protection Distance for Transmission Line Foundation

An insufficient slope protection distance（namely value-A） for tower foundation often appears during completion acceptance.The reasons resulting in this insufficient value-A are analyzed,which include the construction without strict following drawing instructions,measurement errors and design reasons.In case of above circumstances,necessary remedial measures must be taken to ensure safe and stable operation of transmission line,such as retaining wall or masonry backfill.However,,such problem can be solved effectively in the design stage by adopting a deeply-buried dredged foundation or manual-excavated pile foundation in the foundation design for steep terrain.
