Factors Affecting the Measurements and Interpretation of the Vane Strength in Soft Sensitive Clays

Source

Vane tests have been carried out in the field and in the laboratory to investigate some factors affecting the measurements and interpretation of the test, specially the disturbance caused by the insertion of the vane into the clay and the time and shear velocity effects on the strength. Strength rotation curves and failure diagrams have been investigated in the laboratory. The results have shown that the insertion of the vane produces disturbance and generates pore pressure so that the vane strength measured is reduced while time effect leads to an increase in shear strength. Study of the failure diagram shows that the actual shear surface is larger than the cylindrical surface defined by the diameter of the blades.
