Continuous beam bridge construction linear self-adaptive control method based on deformation monitoring radar
The invention provides a continuous beam bridge construction linear self-adaptive control method based on a deformation monitoring radar, which comprises the following steps of: arranging targets on each constructed beam section of a hanging basket and a main beam, and monitoring the deformation of the hanging basket and the deformation of each constructed beam section of the main beam in a construction state and a non-construction state in real time through the deformation monitoring radar; performing comparative analysis on the monitored structural deformation value in the construction stateand the theoretical value, and adjusting construction linear control parameters of each subsequent beam section of the main beam in real time according to a comparative analysis result and an actualstructural deformation rule in a non-construction state, so that the construction linear control parameters are adapted to actual structural deformation; and self-adaptive control over the construction line shape of the continuous beam bridge is achieved. According to the method, the deformation monitoring radar is matched with the target to achieve uninterrupted monitoring of the bridge, the influence of construction condition load changes and the influence of external condition changes in an unconstructed state are considered, the actual line shape of the structure tends to be consistent with the designed line shape, and self-adaptive control over the line shape of the cantilever pouring continuous beam bridge is achieved.
本发明提供了一种基于形变监测雷达的连续梁桥施工线形自适应控制方法，在挂篮和主梁已施工的各梁段布设标靶，通过形变监测雷达实时监测施工状态下和非施工状态下挂篮变形与主梁已施工的各梁段变形，将监测的施工状态下结构变形值与理论值进行对比分析，根据对比分析结果以及非施工状态下结构实际变形规律实时调整主梁后续各梁段施工线形控制参数，使施工线形控制参数与结构实际变形相适应，实现对连续梁桥施工线形的自适应控制。本发明通过形变监测雷达配合标靶实现对桥梁进行不间断监测，考虑施工工况载荷变化的影响以及未施工状态下外部条件变化的影响，使结构实际线形与设计线形趋于一致，实现悬臂浇筑连续梁桥线形的自适应控制。
