LiDAR for Geotechnical Applications

The research intends to focus on four objectives regarding LiDAR within Louisiana Department of Transportation (DOTD) for geotechnical applications: (1) Site investigation and reconnaissance for drilling operations. LiDAR scans identifying slopes and feasible areas for drilling access could save time and efforts, possibly reducing site visits. (2) Geotechnical asset management inventory data collection. LiDAR scans may prove to be an effective way to inventory and characterize slopes, embankments, and culverts. (3) Change detection for use in forensic evaluations and monitoring. LiDAR scans can be utilized to determine volumes and when compared to previous scans can detect changes. This would help identify slope failures, and the extent of remediation efforts. Vicksburg bridge which is experiencing movements would likely benefit from this technology. (4) Cross-section data collection for stability analyses. LiDAR scans could help create fast and efficient cross-sections for use in emergency scenarios where computer analyses and modeling are required for remedial actions regarding slope failures. Cross-section data collection for stability analyses and remediation actions regarding slope failures.
