Large-span ultra-wide steel box girder bridge construction linear control technology
The invention provides a large-span ultra-wide steel box girder bridge construction linear control technology. The technology comprises the following steps: S1, determining design technical standards:determining the design technical standards of road grade, design vehicle speed, bridge floor longitudinal slope, bridge floor transverse slope, bridge structure design reference period, bridge structure design service life and bridge design safety grade; S2, determining bridge installation linear parameters, S4 (after S3), linear influence factor control, and S5, steel arch closure linear control. Theoretical control data during installation are adjusted, the influence of factors such as environment temperature changes is avoided, it is guaranteed that all data of the full-bridge axis, mileage and elevation three-dimensional coordinates are within the control range, and the full-bridge forming line type of the bridge is achieved.
本发明提供了大跨度超宽钢箱梁桥施工线型控制技术，属于技术领域，包括以下步骤，S1、设计技术标准确定，确定道路等级、设计车速、桥面纵坡、桥面横坡、桥梁结构设计基准期、桥梁结构设计使用寿命、桥梁设计安全等级的设计技术标准，步骤S1后的步骤S2、桥梁安装线型参数确定，步骤S3后的步骤S4、线型影响因素控制，步骤S4后的步骤S5、钢拱合龙线型控制。本发明对安装时理论控制数据进行调整，解决了环境温度变化等因素的影响，保证全桥轴线、里程、高程三维坐标各项数据全部在控制范围内，实现桥梁全桥成桥线型。
