采用连续多跨折线型设置的体外预应力高强钢绞线 ,通过两端纵向张拉和各跨中梁底横向张拉的方法加固受弯构件是工程加固处理中的新技术。本文以典型工程实例阐述该技术的方案设计和加固施工方法
The continuous prestressed high-strength steel strand with multi-span folding line type is adopted to reinforce the flexural members by longitudinal tensioning at both ends and lateral tensioning of the mid-span beams. It is a new technology in engineering reinforcement. In this paper, a typical example of the project to illustrate the design of the technology and reinforcement construction methods
