Abstract: The scope of this research has been two fold. The first stage was to develop a Tri Vane Apparatus. The Tri Vane Apparatus uses a miniature vane incorporated into a triaxial cell in order to study the use of the vane in different soils as well as allowing the effects of different vane parameters, such as rotation rate and vane geometry, to be studied in controlled conditions. Initial research was conducted into the history of this device with special emphasis on any previous designs. The design used in the current research has incorporated many design aspects used in these previous devices but has also made several improvements. This leads into the second stage of this research. Since the development of the vane test in 1948 by Cadling and Odenstad (1948), the test has almost exclusively been used for the study of the undrained shear strength of clays. This research has investigated the use of the vane test in sands. Through the use of the Tri Vane Apparatus constructed in the first stage of this research, extensive testing has been conducted on sand, in both isotropic and anisotropic stress conditions.
