| Zusammenfassung |
| Geotechnical hazards along linear transportation corridors are challenging
to identify and often require constant monitoring. Inspecting corridors
using traditional, manual methods requires the engineer to be unnecessarily
exposed to the hazard. It also requires closure of the corridor to ensure
safety of the worker from passing vehicles. This paper identifies the use of
mobile terrestrial LiDAR data as a compliment to traditional field methods.
Mobile terrestrial LiDAR is an emerging remote data collection technique
capable of generating accurate fully three-dimensional virtual models while
driving at speeds up to 100 km/h. Data is collected from a truck that causes
no delays to active traffic nor does it impede corridor use. These resultant
georeferenced data can be used for geomechanical structural feature
identification and kinematic analysis, rockfall path identification and
differential monitoring of rock movement or failure over time. Comparisons
between mobile terrestrial and static LiDAR data collection and analysis are
presented. As well, detailed discussions on workflow procedures for possible
implementation are discussed. Future use of mobile terrestrial LiDAR data
for corridor analysis will focus on repeated surveys and developing dynamic
four-dimensional models, higher resolution data collection. As well,
computationally advanced, spatially accurate, geomechanically controlled
three-dimensional rockfall simulations should be investigated. |
