Paper Title:
Newly Rapid Active Prestressed Strengthening Technique of CFRP Plate and Engineering Application
  Abstract

The actively prestressed strengthening technique of CFRP plate is a kind of strengthening technology with great application in the future. After a comparison and conclusion of the advantages and disadvantages of various prestressed tensile techniques for CFRP plate from home and abroad, based on the WSGG anchor, this paper puts forward the hinged anchor and a new technique where the hinged anchor tensions in vertical direction, the biggest characteristic of this technique is to ensure force uniformity of CFRP plate, consequently, high strength feature of CFRP plate can be fully developed. In addition, a series of improvement have been achieved, such as on-site baiting, fast clamping and rapid tensioning, etc. of CFRP plate. Hinged anchor and its prestressed tensile technique are firstly applied for the reinforced projects of Chongqing Xiaojia River Bridge and Chongqing Lianhua River Bridge, which promote rapid strengthening for the old bridges successfully.
