描述
The Goodman Jack is a borehole tool used for estimating the deformability of rock masses in-situ. It is designed to be used in 3" (76 mm) boreholes.
Two models are available: a twelve piston model for use in hard rock, and a three-piston model for determining the consolidation-time properties of soft rock, soil, and stiff clays.
