Investigation of 3D terrestrial laser scanning techniques for potential application to rock mechanics

摘要

Site characterization of a rock exposure in rock mechanics is one of the important steps, which is required to collect the input data for further rock mechanics analysis, rock engineering design and numerical modeling. However, in the current practice, these data is still obtained by hand including by using compass and inclinometer for fracture mapping, measurement with a ruler, and documentation by recording information on a notebook and photographing with a camera, so the quality and quantity of the data are sometimes unable to meet the requirement in rock engineering projects.
