波形钢腹板连续箱梁桥异步施工法研究

Study on Asynchronous Construction Method of Continuous Box Girder Bridge with Corrugated Steel Webs

异步施工法也称自承重悬臂浇筑法,是基于变截面波形钢腹板连续箱梁桥这种桥型结构自身的特点,形成的一种新型施工方法。将箱型结构的顶板、底板、波形钢腹板划分为3个独立施工面同时施工,优势是节省工期、安全高效。

Asynchronous construction method,also known as self-supporting cantilever casting method,is a new type of construction technology based on the characteristics of the continuous box girder bridge using variable-section with corrugated steel web.The top plate,the bottom plate and the corrugated steel web of the box are divided into three independent parts for construction at the same time,which would improve safety and efficiency with shortened construction period.
