Abstract

A simple torsional vane shear device has been developed which provides a reliable and rapid measure of the shear strength of saturated cohesive soils. This device can be used both in the field and in the laboratory. It is lightweight, inexpensive, and easy to use. For an extensive foundation investigation with a large laboratory testing program, the torsional vane shear device will provide rapid results and will supplement the over-all program. For small investigations, this device can be used in evaluating site conditions and may reduce or, in some cases, eliminate laboratory testing. This paper describes the development and application of the device.
