摘要
以青银高速公路济南黄河大桥斜拉桥钢箱梁安装为实例,对该类水面宽、水深浅,不具备通航和浮运条件的河流上进行钢箱梁安装的方案进行了深入的研究,对几种施工方案进行比选,确定该桥采用顶推施工较为合理,并介绍顶推施工的方法。
Taking the installation of the steel box girder of the cable-stayed bridge of Ji＇nan Huanghe River Bridge on Qingdao-Yinchuan Expressway as an example, this paper conducts a deep-going study of the construction schemes for installation of steel box girders of cable-stayed bridges over similar type of the rivers where the water surfaces are wide, water depth is shallow and which do not have the conditions of navigation and floating transportation, and compares several schemes suitable for the installation of the box girders of the bridges. On the basis of the study and comparison, the paper confirms that the scheme of incremental launching construction to be used for the Ji＇nan Huanghe River Bridge is rational and also introduces in specific detail the method of the incremental launching construction.
