初始状态评估是进行桥梁结构健康监测、评估桥梁运营状态的基础。施工过程结构内力与变形的累积将导致成桥状态与设计值间的差异,以设计值作为桥梁运营评估的初始状态并不合理。本文以之江大桥拱形钢塔斜拉桥为依托,在研究桥梁施工监控与健康监测关系的基础上,分析了进行桥梁结构初始状态评估所需的施工过程特征数据及其提取技术,提出了基于施工过程特征数据的桥梁结构初始状态评估方法。
The initial state assessment is the basis for health monitoring of bridge structure and assessment of the operation status of the bridge. The accumulation of internal forces and deformations in the construction process will lead to the difference between the bridge status and the design value. It is not reasonable to use the design value as the initial status of bridge operation assessment. Based on the bridge girder cable-stayed bridge of Zhijiang Bridge, this paper analyzes the relationship between bridge construction monitoring and health monitoring, and analyzes the construction process characteristic data and its extraction technology required for the initial state of the bridge structure. Evaluation Method of Initial State of Bridge Structure Based on Construction Process Characteristic Data.
