摘要
青海—西藏±500 kV直流联网输电线路工程,线路所经区域自然条件十分恶劣,为满足工程工期要求,保证冬季施工的混凝土质量,减少现场人工作业量,提高施工效率,本工程在部分地区基础设计考虑采用钢筋混凝土预制装配式基础。文章对这一地区的地基土及地下水(冰)具有不同程度的腐蚀性进行了分析研究,提出了预制装配式基础防腐设计方案及施工措施。
The natural condition of ± 500 kV Qinghai - Tibet DC interconnecting transmission engineering passing areas is rather inferior, in order to meet the requirement of the time limit for the project, and ensure the concrete quality of winter construction, as well as reduce the field manual work and improve the efficiency of construction, some parts of the engineering considers to adopt the reinforced concrete prefabricated assembly foundation. The paper makes analysis and study on the different corrosion degree of the region＇ s base earth and ground water or ice, and proposes prefabricated assembly foundation anti -corrosion design scheme and construction measures.
