摘要

Bridges are important public assets and need periodic inspection. Excessive deformation or damages occurring at the main load-carrying members frequently raise concerns and detailed inspections are scheduled according to the judgment of field investigators. It is desirable to measure overall spatial information in a short period of time in order for decision makers to prevent disaster. To propose a standard procedure at routine bridge inspections using three-dimensional (3-D) laser scanners, the research team designed 3 full-scale tests to streamline equipment setup, data acquisition, precision assessment and the post-processing program. The final results suggest that 3-D laser scanners showing high-precision measuring capacity are suitable for and capable of obtaining 3-D measurements as required in a short time. The technology should be promoted for use during routine inspections of bridges to acquire the displacement information of critical structural elements for rapid safety evaluations. This paper proposes a working procedure summarizing lessons learned in the test program.
