摘要
湛江海湾大桥水中引桥采用跨度50 m的预应力混凝土连续箱梁,采用移动模架系统现浇施工。为保证施工安全及桥梁线形准确,对移动模架系统的静载试验及第1孔梁混凝土浇注和移动模架的前移过程进行监测。
The offshore approach spans of Zhanjiang Bay Bridge are designed to use 50-m span prestressed concrete continuous box girders that are to be cast in situ with slide shuttering system. To ensure the construction safety and correct geometry of the approach spans, the authors in this paper completed monitoring of static load test process of the slide shuttering system, and also monitoring of concrete casting of the first span girder of the approach spans and forwarding process of the system.
