Building a Rockfall Database Using Remote Sensing: Techniques for Hazard Management in Canadian Rail Corridors
The section of CN railway between Vancouver and Kamloops runs along the base of many hazardous slopes, including the White Canyon, which is located just outside the town of Lytton, BC. The slope has a history of frequent ...
A Bayesian Approach to Convergence Detection in Underground Excavations using LiDAR
This thesis deals with the subject of convergence detection in underground excavations --- typically mining operations. Traditional methods for convergence monitoring involve operose surveying procedures that produce ...
Stress Inversion Using LiDAR Tunnel Deformation Measurements
Far-field stresses are those present in a volume of rock prior to excavations being created. Estimates of the orientation and magnitude of far-field stresses, often used in mine design, are generally obtained by single-point ...
Towards Mapping of Rock Walls Using a UAV-Mounted 2D Laser Scanner in GPS Denied Environments
In geotechnical engineering, the stability of rock excavations and walls is estimated by using tools that include a map of the orientations of exposed rock faces. However, measuring these orientations by using conventional ...
