include the following tests, and their use in peat and organic soils was reviewed by
Edil (2001).
(a) Vane shear test
The miniature vane shear test may be used to obtain estimates of the undrained
shear strength of fine-grained soils. The test provides a rapid determination of
the shear strength on undisturbed, remoulded or reconstituted soils. Field vane
shear tests provide an indication of the
in situ
undrained shear strength of fine-
grained clays and silts or other fine geomaterials, such as mine tailings, organic
muck and substances where undrained strength determination is required. The test
