Cable-stayed suspension cooperative system bridge girder linear control method
The invention relates to a cable-stayed suspension cooperative system bridge girder linear control method which comprises the following steps: firstly, after independently completing construction of a cable-stayed structure system and a suspension cable structure system, then erecting an intersection area beam section between a cable-stayed area beam section and a suspension area beam section, and dividing the intersection area beam section into an intersection area cable-stayed side beam section and an intersection area suspension side beam section; then the cross area cable-stayed side beam sections are installed in a designed camber line shape according to a cable-stayed area beam section erecting method, and the cross area suspension side beam sections are installed in the sequence of first hinging and then rigid connection according to a suspension area beam section erecting method; then, the temporary restraining device between the cable-stayed area beam section and the main tower is removed, remaining stay cables and slings of the cross area beam section are installed, and system conversion is completed; and finally, carrying out side span weight concrete and second-stage dead load construction, actually measuring the line shape of the main beam in the construction process, checking the deviation between the actual line shape and the designed line shape, and realizing the matching of the actual line shape and the designed bridge line shape by adjusting the cable force of the stay cable and the sling.
本申请涉及一种斜拉悬吊协作体系桥主梁线形控制方法，包括：首先在独立完成斜拉结构体系和悬索结构体系施工后，其次在斜拉区梁段和悬吊区梁段之间架设交叉区梁段，交叉区梁段被分为交叉区斜拉侧梁段和交叉区悬吊侧梁段；然后交叉区斜拉侧梁段按照斜拉区梁段架设方法以设计拱度线形安装，交叉区悬吊侧梁段按照悬吊区梁段架设方法先铰接后刚接顺序安装；接下来解除斜拉区梁段与主塔间的临时约束装置，进行交叉区梁段剩余斜拉索及吊索安装，完成体系转换；最后在边跨压重混凝土、二期恒载施工，施工过程中实测主梁线形，核算实际线形与设计线形间的偏差，通过调整斜拉索及吊索索力，实现实际线形与设计成桥线形吻合。
