Assessing Geometry of Rock Masses using Static and Mobile LiDAR Scanning

چکیده
Transportation corridor management is regularly performed for evaluation of road conditions, hazards, and planning, and is traditionally based on the manual inspection of the corridors. Recent research projects have evaluated advanced remote sensing technologies, such as LiDAR and photogrammetry, to replace preliminary field evaluations with desktop studies through evaluation of 3d sensor data. This research has demonstrated the applicability of both static and mobile terrestrial LiDAR to improving transportation corridor management systems. Through rapid deployment in combination with versatile scanning techniques and data processing options, LiDAR has become a state-of-the-art technology for transportation corridor analysis and management. LiDAR data can be used for rockmass evaluation, change detection, rockfall hazard evaluation, as well as numerous standard survey measurements. RÉSUMÉ La gestion des corridors de transport est effectuée regulièrement par les ministères de transport pour évaluer l'état des routes, les risques, et pour la planification. Traditionellement, ces activités ont été faites par une inspection manuelle des corridors. Certains récents projets de recherche à grande échelle au Canada et à l'étranger ont évalué les technologies de la télédétection de pointe, tels que le LiDAR et la photogrammétrie, afin de remplacer les évaluations préliminaires menées sur le terrain avec l'évaluation des données à l'ordinateur. Les résultats de cette recherche ont démontré l'applicabilité du LiDAR statique et du LiDAR mobile terrestre à l'amélioration des systèmes de gestion des corridors de transport. La combinaison de sa deploiement rapide, ses moyens d'auscultation polyvalents, et plusieurs options pour la traitement des données a permis au LiDAR de devenir une technologie de pointe pour l'analyse et la gestion des corridors de transport. Les données du LiDAR peuvent être utilisées pour l'évaluation de masses rocheuses, la détection automatisée des changements, l'évaluation du danger d'une chute de pierres, ainsi que pour effectuer de nombreuses mesures d'arpentage standards.

Verification of a 3-D LiDAR point cloud viewer for measuring discontinuity orientations
LiDAR (Light Detection and Ranging) scanners are increasingly being used to measure discontinuity orientations on rock cuts to eliminate the bias and hazards of manual measurements which are also time consuming and somewhat subjective. Typically LiDAR data sets (point clouds) are analyzed by sophisticated algorithms that break down when conditions are not ideal, eg. when some of the discontinui...
متن کاملPrediction of the deformation modulus of rock masses using Artificial Neural Networks and Regression methods
Static deformation modulus is recognized as one of the most important parameters governing the behavior of rock masses. Predictive models for the mechanical properties of rock masses have been used in rock engineering because direct measurement of the properties is difficult due to time and cost constraints. In this method the deformation modulus is estimated indirectly from classification syst...
متن کاملThe Effect of Lower Detachment Zone on Buckle Folds Geometry
Buckle folds are common traps for hydrocarbon in several contractional provinces. Buckle folds form where stratified sequences rest a top salt or some other utterly weak rock as a decollemet zone in units with high competency contrasts by a compressive stress which acted along the length of the rock layers. An important parameter affecting buckle folding of a competent zone above a mobile decol...

Mobile Mapping Systems (MMS) are now commonly acquiring lidar scans of urban environments for an increasing number of applications such as 3D reconstruction and mapping, urban planning, urban furniture monitoring, practicability assessment for persons with reduced mobility (PRM)... MMS acquisitions are usually huge enough to incur a usability bottleneck for the increasing number of non-expert u...
متن کاملNumerical probabilistic analysis for slope stability in fractured rock masses using DFN-DEM approach
Due to existence of uncertainties in input geometrical properties of fractures, there is not any unique solution for assessing the stability of slopes in jointed rock masses. Therefore, the necessity of applying probabilistic analysis in these cases is inevitable. In this study a probabilistic analysis procedure together with relevant algorithms are developed using Discrete Fracture Network-Dis...
