摘要
随着我国西北大开发战略的实施,西北地区输电线路电压等级越来越高,因此西北地区高海拔、高寒地区的输电线路基础选型的研究,对于西北地区高电压等级的建设、运行维护都有着十分重要的意义.结合青海地区 750 kV输电线路工程的基础设计情况,对薄覆盖层岩石地基、厚覆盖层岩石地基、一般土质地基、河网地基等不同地基条件下输电线路基础选型进行了分析.
Abstract
With the continuous promotion of China's Northwest Development Strategy,the voltage grade of transmission line in northwest China has become higher and higher.Survey on pole foundation type selection for transmission lines in plateau area there is of great significance to construction,operation and maintenance of high voltage grade projects.Based on the foundation design of 750 kV transmission line project in Qinghai province,the foundation type selection under four different foundation conditions,such as thin overburden rock foundation,thick overburden rock foundation,general soil foundation and river network foundation,is studied and analyzed.
