大直径缓粘结预应力施工技术在工程中的应用

The Application of Large Diameter Retard-bonded Prestressed Construction Technique in Engineering

缓粘结预应力技术具有结构可靠和施工方便等优点,近几十年来,经过国内外科研、设计、施工等单位的应用,该技术已经有很多成功的实践案例。本文通过对安顺高铁站站前广场结构内大直径缓粘结预应力的应用,介绍了其在结构的施工中的方法和应该注意的问题。

Retard-bonded prestressed structure has advantage of structural reliability and convenient construction. In recent decades,this technology has many successful practice cases through the application by scientific research,design,construction and other units at home and abroad.In the paper,through the application of Anshun high-speed station square structure in large diameter retard-bonded prestressed,introduces its method and the problems we should be paid attention to in the construction of the structure.
