英文摘要	Meso-fabric of gravel particles is not only a reflection of the unique sedimentary history, but also directly affects the geotechnical properties of moraine soil. However, there are few researches on it so far in geotechnical engineering field, due to the difficulty of obtaining undisturbed moraine soil sample. To change this situation, we succeeded in getting undisturbed moraine soil samples from the west side of the Yulong Snow Mountain with the delicate manual cutting work. We scaned the 6 pieces of moraine soil samples by CT instrument and obtained the real meso-fabric images of internal moraine soil for the first time. After CT images binarization and denoising processing with the help of Matlab, section fabric indexes of stone area ratio, grain orientation and particle shape of moraine soil gravel particles were described with conventional statistical methods. The results show that the differences between vertical sections are little, but the differences between vertical sections and horizontal sections are much more obvious.
