镇江长江500kV大跨越北塔塔高180m,钢结构,由意大利SAE公司设计。地基分析和基础处理由SAE公司委托意大利岩土工程研究所负责。地质资料由能源部华东电力设计院提供。北岸跨越塔和耐张塔均位于第四纪近代长江冲积层之上,地层由软可塑的亚粘土、轻亚粘土和粉砂组成。塔位所在地区的地震基本烈度为7°,考虑到本工程的重要性,经国家计委审查批准抗震设防烈度为8°。
Zhenjiang Changjiang 500kV spanning 180 meters north tower, steel structure, designed by the Italian SAE company. Ground-based analysis and basic treatment were entrusted by SAE to the Italian Institute of Geotechnical Engineering. Geological data is provided by East China Electric Power Design Institute of the Ministry of Energy. The north bank crossing tower and the tension tower are all located on the alluvial layers of the Yangtze River in the Quaternary period. The formation consists of soft clay subclay, light sub-clay and silt. The earthquake intensity in the area where the tower is located is 7°. Considering the importance of this project, the intensity of seismic fortification is 8° after review and approval by the State Planning Commission.
