桥梁加固中预应力新技术的应用

The application of new prestressing force technology in bridge reinforcing

在分析目前国内桥梁加固现状的基础上,强调了预应力主动加固思想在设计中的重要性,综述了近年来几种国内外旧桥加固中运用的预应力新技术——预应力高强复合材料(PFRP)加固技术、SRAP法加固技术等,并列举了工程实例。

On the basis of analyzing the present reinforcing situations of bridges at home now, the article emphasized the importance of prestressing force positive reinforcing thought in the design. The article sums up several new prestressing force techniques of old bridge reinforcing at home and abroad in recent years Prestressed Fiber Reinforced Polymer material（PFRP） reinforcing technique, SRAP reinforcing technique and so on, and listing some project example.
