一、前言采用高强钢丝、钢绞线作预应力混凝土配筋具有缩小构件断面,提高承载力及加大跨度等优点。对改革肥梁胖柱、解决深基重载、大跨、高层及耐高压容器等建筑结构均已收到良好的技术经济效益。因此在各种建筑工程中得到广泛的应用。但是在海洋环境中,使用高强钢丝、钢绞 First, the preface The use of high-strength steel wire, steel strand for prestressed concrete reinforcement has the advantages of reducing the cross-section of the component, increase the carrying capacity and increase span. On the reform Fat fat column, to solve the deep base heavy load, large span, high-pressure containers and other building structures have received good technical and economic benefits. Therefore, a variety of construction projects have been widely used. However, in the marine environment, the use of high-strength steel wire, steel
