摘要
为了解决电力杆塔基础在青藏高原多年冻土中的稳定,在高温冻土地段使用热棒技术处理冻土的地温,使不稳定性的多年冻土转变为稳定性的多年冻土,从而确保杆塔基础可靠稳定,线路安全运行。
In order to solve the foundation stability problem of electric power tower in permafrost zone in Qinghai-Tibet Plateau, the hot rod technology was used in high temperature permafrost area to deal with the ground temperature of permafrost. Then the unstable permafrost changed into stable permafrost,which ensures the stability of tower foundation and safe operation of transmission lines.
