摘要
随着特高压工程快速建设,线路走廊紧张,途径高山或丘陵地区线路路径占比较大,机械化程度高的岩石锚杆基础应用比例逐步提高,对岩石锚杆基础破坏模式、锚固长度、极限抗剪强度参数取值等方面提出建议,为特高压工程中推广应用提供参考。
With the quick construction of UHV power transmission lines,the share of the hilly-mountains region has more percent in the power transmission line terrain. the ratio of the rock anchor foundation applied in power transmission line is increasing gradually. Combining theory study with field prototype test,some suggestion are proposed in this paper about the failure mode,anchored length,the limit shearing strength,to provide a reference for future application.
