ABSTRACT: Light detection and ranging (Lidar) is becoming more widely used in the geotechnical community as its number of applications increase. It has been shown to be useful in tunnel for applications such as rockmass characterization and discontinuity measurements. Lidar data can also be used to measure deformation in tunnels, but before a comprehensive methodology can be developed, the accuracy issues associated with scanning must be fully understood.
RÉSUMÉ: Light Detection and Ranging (Lidar) est de plus en plus largement utilisés dans la communauté géotechnique que le nombre de ses applications augmentent. Il a été montré pour être utile dans le tunnel pour des applications telles que la caractérisation masse rocheuse et les mesures de discontinuité. Les données lidar peut aussi être utilisé pour mesurer la déformation dans les tunnels, mais avant une méthodologie complète peut être développée, les questions associées à la précision de numérisation doit être pleinement compris.
