摘要
针对盐湖地区盐渍土强腐蚀性、地基土软弱、地下水位高等特殊地质条件,结合新疆与西北主网联网750 kV第二通道输变电线路工程杆塔基础大荷载作用情况,进行了盐湖地区杆塔基础设计选型与方案优化,提出了采用玻璃钢护套包裹进行防腐处理的斜柱式基础,并总结了其关键施工技术。结果表明采用玻璃钢护套进行防腐处理的斜柱式基础可在盐湖地区输电线路杆塔基础工程中推广应用。
Not only concerned with the special geological conditions in salt lake area, such as strong corrosion of saline soil, weakness of foundation soil, high water table of groundwater and so on, but also based on the consideration of large tower foundation loads of the Second 750 kV Power Transmission and Transformation Project of Xinjiang power grid interconnected with northwest main power grid, design selection analysis and optimal solution research is conducted. The pad and chimney foundation with anti-corrosion protective cover of FRP is proposed and the key construction technology is summarized. The resuhs show that application of the pad and chimney foundation with anti-corrosion protective cover of FRP in salt lake area can be popularized in transmission line tower foundation engineering.
