Doctoral Dissertations

"Terrestrial Laser Scanning (TLS) technology has been used for predicting and researching geological hazards for two decades. This research focuses on using LiDAR (Light Detection And Ranging) to measure the slow-moving displacement of both surface and subsurface soil of landslides. Two kinds of computer simulation software, FLAC3D® and PFC3D® were used to simulate the landslide process to compare with the LiDAR scanning results.

The primary contributions from this research are as follows:

1. Several error tests were done to prove that the three-dimensional LiDAR scanner used in this research can precisely obtain the three-dimensional position, the displacement and the rotational …
