A REVIEW OF THE VANE TEST

THE THEORY AND PRACTICE IS REVIEWED IN MATERIALS WITH ZERO ANGLES OF SHEARING RESISTANCE ALONG WITH THOSE SANDS, SANDY CLAYS, FISSURED CLAYS AND PARTIALLY SATURATED CLAYS WHICH OFTEN EXHIBIT AN ANGLE OF SHEARING RESISTANCE IN THE UNDRAINED TRIAXIAL TEST. IT IS SHOWN THAT THE THEORY OF THE VANE TEST IN ZERO ANGLE OF SHEARING RESISTANCE MATERIALS IS INVESTIGATIONS AND IN-SITU FAILURES CONFIRM THIS THEORETICAL WORK. THE VANE TEST CAN THEREFORE BE USED WITH CONFIDENCE FOR SHORT TERM END OF CONSTRUCTION ANALYSES IN NON-FISSURED, SATURATED CLAYS. THE TEST HAS BEEN FOUND TO BE EXTREMELY USEFUL IN THE VERY SOFT AND THE VERY SENSITIVE CLAY SOILS. THE EXPERIMENTAL RESULTS OF VANE TESTS IN FISSURED CLAYS, SANDY CLAYS AND SANDS WHICH GIVE AN ANGLE OF SHEARING RESISTANCE IN THE UNDRAINED TRIAXIAL TEST, ARE DESCRIBED. LITTLE CORRELATION WITH ANY OF THE EXISTING THEORIES HAS BEEN DETERMINED. AS THE MECHANICS OF THE VANE TEST IN INSERTING AND ROTATING THE VANE IN THESE SOILS IS EXTREMELY COMPLEX, IT IS RECOMMENDED THAT THEIR BEHAVIOR BE DETERMINED IN THE TRIAXIAL TEST, WHERE THE STRESS CONDITIONS CAN BE MORE CLOSELY CONTROLLED.
