摘要
预弯组合梁是近年在国内采用的新梁型 ,已经在许多小跨度桥上成功应用 ,在大跨度桥上也开始付诸实践。结合预弯组合梁的特点和施工实践 ,对上海市莘奉金高速公路北段立交桥 4 0m大跨度预弯组合梁的施工技术进行分析 ,说明预弯组合梁在城市桥梁建设中具有广阔应用前景。
The preflex composite girder is a new girder type that has been successfully used in small span bridges in China in the recent years, and is currently starting to be used in long span bridges. In the light of the characteristics and construction practice of the composite girder, this paper analyzes the construction techniques of 40 m long span preflex composite girders used on a grade separation bridge on the north section of Shenfengjin Expressway in Shanghai, and demonstrates the broad prospective of application of such type of girder to urban bridge construction.
