摘要
结合工程实际,阐述了体外预应力加固技术的设计方法和施工工艺,包括体外预应力加固设计步骤、束形选择与优化、锚固节点和转向器的构造要求等。实践证明,体外预应力加固技术是一种经济适用、施工简单、效果显著的加固方法,值得推广。
The externally prestressed structural system means a prestressed structural system formed by prestressing cables arranged outside the structural element. Based on an engineering project, the design method and construction technics of external prestressing reinforcement technology is expound. Including the step of reinforcement design, the choice and optimize of external tendons, the structure demand of anchorage joints and deviators. It is proved by practices that external prestressing strengthening is an economic method with distinct effect which is simple to construction and worthy.
