Linear control method for steel-concrete combined bridge tower in construction stage
The invention discloses a linear control method for a steel-concrete combined bridge tower in a construction stage, which belongs to the technical field of bridge construction, and comprises the following steps: acquiring the size of a to-be-assembled section of the bridge tower, establishing a model according to the construction stage based on a theoretical linear shape, and calculating the displacement of each section of the bridge tower in the assembling construction stage based on a zero initial displacement method. Determining the initial displacement of the to-be-assembled section of the bridge tower along the tangential direction of the assembled section; calculating the total displacement and the rotation angle of each section of the bridge tower in the splicing construction process, preliminarily obtaining the line type of the bridge tower in the bridge forming stage, and obtaining the manufacturing line type of the bridge tower; and performing forward analysis and calculation on the finished bridge displacement, performing multiple iterations by taking the limit value of the displacement difference value of each section of the bridge tower in the finished bridge stage as a target, correcting the manufacturing line type of the bridge tower, and obtaining the corrected line type of the bridge tower in the finished bridge stage. According to the method, the deviation between the line type of the bridge tower in the bridge forming stage and the line type of the theoretical design can meet the precision requirement by shifting according to the pre-calculated rotation angle and displacement before construction.
本发明公开了一种钢混组合桥塔的施工阶段线型控制方法，属于桥梁施工技术领域，获取桥塔待拼装节段的尺寸，基于理论线形按施工阶段建立模型，基于零初始位移法计算桥塔各节段在拼装施工阶段产生的位移，确定桥塔待拼装节段沿已拼装节段切线方向的初始位移；计算拼装施工过程中桥塔各节段的总位移及转角，初步得到成桥阶段的桥塔线型，获取桥塔的制造线型；正装分析计算成桥位移，以成桥阶段的桥塔各节段位移差值的限值为目标进行多次迭代，对桥塔的制造线型进行修正，获取修正后的成桥阶段桥塔线型。该方法能够通过在施工前以预先计算的转角和位移量进行偏移，保证成桥阶段的桥塔线型与理论设计线型的偏差满足精度要求。
