Abstract

This research presents the application of the 3D Laser Scanning Technology for monitoring and inspection of Cable-stayed bridge. The Rama IX bridge is selected as the case study. The Rama IX bridge is the main connector bridge between Thonburi and Bangkok sides, as a part of the first Expressway in Thailand since 1987. The structure health monitoring and inspection is an essential process to ensure the bridge's safety and serviceability. This research applied the terrestrial laser scanner to collect the current three-dimensional surface configurations of the Rama IX bridge. According to the scanning data, the 3D point cloud model of the bridge can be developed. The current dimensions, elevations, slope, and the bridge's cross-section are then presented. Finally, the potential of using laser scanning data for cable configuration measurement is also highlighted.
