Safety monitoring of large cantilever bridge construction based on multi-source data measurement

Abstract

Bridge engineering construction is a kind of engineering construction with high risk. Only by building scientific and reasonable safety assessment and monitoring measures can the construction safety be improved and the risk be controlled. Based on the construction of a large cantilever steel truss traffic bridge project, this paper introduces the application of three-dimensional laser scanning technology in the monitoring of bridge transverse construction from the aspects of measuring point layout, monitoring scheme, scanning measurement and data analysis and processing. This paper introduces the bridge construction safety monitoring technology, as well as the content and steps of construction safety monitoring, and summarizes the measures of bridge construction safety assessment monitoring.
