摘要
大跨越输电线路杆塔在运行中需承受较大的水平、抗拔及抗压作用力,其安全标准较普通输电线路杆塔更高。针对杆塔的沉降问题,以±800 kV电压等级杆塔为研究对象,基于国家和行业标准,先后进行了4次精确观测。结果表明,虽然部分塔基变化值较大,但杆塔整体仍然处于安全范围之内。
Large span transmission line towers need to withstand significant horizontal,tensile,and compressive forces during operation,and their safety standards are higher than those of ordinary transmission line towers.Regarding the settlement issue of towers,four precise observations were conducted based on national and industry standards,with±800 kV voltage level towers as the research object.The results indicate that although there are significant changes in some tower foundations,the entire tower is still within the safe range.
