The Vane Shear Tester takes direct readings of
shear strength to depths up to 3 meters (10 ft). Three vane sizes
allow for the direct determination of undrained shear strength
of soft to stiff clays. The peak vane value is determined by a
calibrated scale ring built into the head assembly. The cross handle
is used both to push the vane to the desired test depth and apply
the shearing torque. To correct for the skin friction of the extension
rods, a dummy probe replaces the vane and a skin friction test
is performed adjacent to the vane test location.
