输电线路杆塔基础砂岩崩解特性试验研究

摘要

Taking the area representative red sandstone as the research object of Juntang-Xi’er 110 kV transmission line engineering construction by Anhui Xuancheng mountainous area,this paper carried out the dry and wet cycle indoor disintegration test,through the analysis on disintegra-tion phenomenon and disintegration thing particles,discussed the regularity and mechanism of sandstone disintegration,put forward construction suggestions of transmission line tower foundation.%选取安徽宣城山区建设的军塘—西二110 kV 输电线路工程区域代表性红砂岩为研究对象，开展了干湿循环室内崩解试验，通过分析崩解现象与崩解物颗粒，探讨了砂岩崩解的规律及机理，据此提出了输电线路杆塔基础的施工建议。
