| In this study, a new methodology by using the X-ray CT scan is proposed for estimating void ratio of sandy soil. The general problems in high resolution X-ray CT scan such as beam hardening and ring artifact had been successfully settled up using thin metal plate filter and some calibration process. In order to calculate the void ratio of sand from its CT image, the procedures and algorithm for CT image processing are developed. CT scan tests for Joomunjin sand are carried out to verify its applicability to void ratio testing. |
