Description
Technical Field
The application belongs to the field of bridge construction monitoring, and particularly relates to a bridge deformation monitoring method and a bridge deformation monitoring system.
Background
The deformation monitoring of the bridge is an important content of bridge monitoring engineering, and the deformation monitoring of the bridge accurately detects the deformation condition of the bridge by adopting various deformation detection technologies, thereby having an important guarantee function on the safety performance of the bridge engineering.
The existing bridge deformation monitoring method has the following defects: firstly, the existing bridge deformation monitoring method often identifies and confirms the structural state of the bridge after the bridge is formed, so as to judge whether the bridge is deformed, and does not carry out stepwise real-time monitoring on the bridge deformation in the bridge construction process. When the bridge is deformed in a certain construction process and is not found in time, particularly the deformation in a basic construction process, and the full bridge construction is monitored after the full bridge construction is completed, only the full bridge can be maintained or rebuilt, resources are wasted, and economic loss is caused. Secondly, when the deformation of the bridge pier is monitored, the deformation of the internal structure of the bridge pier is mainly analyzed from the angles of horizontal displacement and settlement displacement of the bridge pier, and the deformation of the internal structure of the bridge pier is not considered; and the deformation of the internal structure of the bridge pier can affect the bearing performance of the bridge pier, so that potential safety hazards are generated. Thirdly, when bridge deck deformation is monitored, analysis is mainly carried out from the appearance level of the bridge deck, such as cracks, pits and the like on the surface of the bridge deck, the deflection of the bridge deck is not considered, the bridge deck deforms under the action of external load, and the actual line shape and the design line shape of the bridge are different, so that the internal stress state of the bridge is influenced. Excessive bridge deck line change not only affects driving safety, but also has direct influence on the service life of the bridge.
