EVALUATION OF PARTICLE CRUSHING IN SOILS USING X-RAY CT DATA

摘要

The objective of this paper is to evaluate particle crushing in the soil using the results of X-ray CT scanning without any destruction and sampling. First of all, the properties of X-ray CT data are discussed using its statistical consideration. Then, a method for evaluating particle crushing is proposed. This method is implemented by scanning simple granular materials using aluminum rods and soil. Then, a series of model pile loading tests are conducted for the materials of non-crushable and crushable soils. Based on the results of CT scanning for the model grounds, the effectiveness of the proposed method for evaluating particle crushing using X-ray CT data is confirmed. Finally, one of the effective usages of X-ray CT data in geotechnical engineering is convinced.
