摘要
该文在分析目前国内外公路桥梁运行现状的基础上,综述了近年来几种国内外旧桥加固的新技术——复合材料(FRP)加固技术、SRAP法加固技术、植筋加固桥面技术、填芯法加固技术和直接喷涂法加固技术,并评述各自优缺点。最后在评述以上新技术以及其他已成熟应用技术的基础上,给出桥梁加固工程的几点实际应用原则,并展望了未来加固技术。
On the basis of analyzing the present operating situations of highway bridges at home and abroad now, the article sums up several new techniques of old bridge reinforcing at home and abroad in recent years-composite material (FRP) reinforcing technique, SRAP reinforcing technique, planting-bar reinforcing deck technique, filling-core reinforcing technique and direct spraying reinforcing technique, and evaluates each advantages and disadvantages. Finally, on the basis of evaluating the above new techniques and the other well-considered applied techniques, the article gives several practical application principles of the bridge reinforcing projects, and looks into the future reinforcing techniques.
