Since particular soil structures are formed by the shear failure and the following shear creep caused by landslide, the study on the soil structures is important to make the mechanism of landslide clear.
The authors made a direct shear test apparatus as a trial in order to study the progress of the soil structures of shear layer in process of shear test.
The structural features of the apparatus are that shear boxes have 600mm length, the shear deformation of the boxes can be theoretically established from 0mm to 600mm in order to form the soil structures by long shear creep, and the boxes can be disjointed with simple procedures in order to sample the undisturbed soil structures.
We were able to make it clear, with the apparatus, that almost deformations in the length direction of the sample are about uniform, and the particular soil structures are formed in the creep layer. Therefor we conclude that the apparatus is available for the same kind of study.
