Ｘ線ＣＴスキャンを活用した土の侵食抵抗試験に関する基礎的研究

抄録

In this study, the test equipment was manufactured by applying the sprayer, and the erosion resistance test was carried out. X-ray CT scan was used for interpretation of the test results, and not only the development state of the root system in the test specimen was grasped, but X-ray CT scan was also carried out after the test to determine the erosion depth and erosion rate.

The test results revealed that the erosion resistance increased as the root system developed. In addition, the root system quantity and erosion depth obtained from the X-ray CT scan image of the test specimen had a negative correlation, and it was found that the X-ray CT scan was useful as one of the methods for grasping the influence of the root system on the erosion resistance of soil.
