Bridge deformation monitoring method

Abstract

The invention relates to a bridge deformation monitoring method. The method mainly comprises the following steps: 1, selecting a radar remote sensing satellite SAR image data source, and completely covering bridge infrastructures in research time and geographic space dimensions; 2, performing interference processing on the selected SAR image data source based on a timing sequence SBAS-InSAR technology to obtain detailed deformation information of the research bridge infrastructure within the monitoring time; and 3, performing point-line statistical analysis on the detailed deformation information of the bridge facility obtained in the step 2, and evaluating and researching the deformation evolution trend of the bridge facility. According to the method, the technical superiority of a novelSBAS-InSAR monitoring means compared with a traditional monitoring means is well reflected, and the reliability and scientificity of bridge facility monitoring results are greatly improved in combination with a point-line statistical analysis method of the SBAS-InSAR technology. Interval and point-line type evaluation is carried out on bridge deformation monitoring, and the reliability of the SBAS-InSAR technology for bridge infrastructure deformation monitoring is greatly improved.

Description

technical field [0001] The invention relates to the technical field of bridge infrastructure monitoring deformation, in particular to a bridge deformation monitoring method. Background technique [0002] Bridges are an important part of public transportation, an important link in the road network and railway network, and the throat to ensure that all roads are open to traffic. As an important transportation facility, bridges play a fundamental role in ensuring and promoting social and economic development. However, after the bridge is completed and opened to traffic, due to factors such as climate, increasing traffic volume, and serious overloading, the bridge is gradually aging and fatigued, posing serious safety hazards. Once the bridge is damaged or collapsed, the economic loss caused is immeasurable, and even the price of life will be paid. [0003] The real-time monitoring project of bridge infrastructure has become an increasingly important hot work in the current er...
