摘要
在新建输电线路与旧线路出现交叉跨越时,往往需要对旧线路进行升高或降低改造,需要对相应杆塔结构、弧垂、摇摆角、上拔进行重新验算,确定方案是否可行,同时采取必要的加强措施。
In the scissors crossing of new transmission lines and the old ones, the old lines often need to increase or change. The structure, sag, swing angle and uplift of corresponding tower should be checked again to determine the feasibility of the program. It is necessary to take strengthened measures.
