摘要
为研究特高压输电塔的抗震性能,以1 000 kV"皖电东送"淮南—上海输变电工程同塔双回路SZ272P钢管塔和晋东南—南阳—荆门输电线路酒杯型ZBS1角钢直线塔为原型,依据相似理论进行分析,设计并制作缩尺振动台试验模型,分别进行单塔、单塔挂质量块和塔线耦联体系地震模拟振动台试验,验证了1 000 kV钢管和角钢模型塔在8度罕遇地震作用下的抗震性能,提出了抗震设计改进建议。
In order to study the seismic performance of UHV transmission tower, taking the SZ272P steel tube tower in double-circuit 1 000 kV Huainan-Shanghai transmission line and the ZBS1 cup-type angle line tower in Jindongnan-Jingmeng transmission as project background, this paper designed and made the scale model of shaking table test, based on the similarity theory. Three cases of the models, single tower, tower with concentrated mass to simulate the conductors and tower-conductor coupled system, were tested on the shaking table, whose results verified the seismic performance of the 1 000 kV steel tube tower and the angle tower in the rare earthquake of 8 degree. Finally, some suggestions for seismic design were proposed.
