連接巴西的里約热內卢和尼泰罗伊两城市,跨越瓜納巴那海湾的长7884m、寬26.6m的桥,其預应力混凝土上部結构采用环氧树脂将預制段胶粘在一起的悬臂施工法。曾以桥的模型进行胶粘接縫的实驗研究,证明胶粘接缝并不影响結构的安全。为测定施工时安裝操作有关的胶粘接縫的各种重要特征,曾进行了一些研究。并以特制的混凝上試块,对胶粘接縫的性能进行研究。
Connecting the Brazilian cities of Rio de Janeiro and Niteroi with 7884m long and 26.6m wide bridges across the Gulf of Guanajuato, the prestressed concrete superstructure is epoxy-bonded to prefabricated sections Cantilever construction method. Had bridge model experimental study of adhesive joints, that adhesive joints do not affect the safety of the structure. A number of studies have been conducted to determine the various important features of adhesive joints related to installation operations during construction. And to a special coagulation on the test block, the performance of the adhesive seams.
