SOIL：[MECHANICAL TEST]High Speed Ring Shear Testing Apparatuss
MIS-233-1-75
[Outline of Product Technology]
This apparatus replicates rapid changes of the effective stress generated by earthquakes or other events,
and is appropriate for research of rapid landslide such as avalanche of earth and rocks.
The acrylic made cells enables observation of the shear status from the outside.
