Abstract
Earth reinforcement technigue has been widely used around the world and so far, many research projects for both experimental and analytical aspects such as model testing and numerical analysis have been conducted. However, an interaction mechanism between soil and geogrid is still on going issues and the real behavior has not been observed precisely. Recently, an X-ray CT scanner became a useful tool even for geotechnical engineering as a nondestructive testing apparatus. It is well known that the results from CT scanning can be realized as the change of the density in the material. This apparatus produces visual images in three demension. The objective of this paper is to visualize the interaction mechanism between soil and reinforcement under pull-out test using industrial X-ray CT scanner.
