Resumen:
The Field Vane Test is used to determine undrained shear strength of cohesive soils, by pushing a rectangular vane body into cohesive soil and rotating it. During rotation the torque and rotation are measured. From the measured torque and the dimensions of the vane the undrained shear strength can be derived. With this test the remoulded strength can also be measured. The tests are carried out in boreholes as well as with pushed in types or down hole types. The torque and rotation are normally measured at ground level using extension rods; with downhole types the torque and rotation are measured just above the vane body. For field vane testing three methods are commonly used: 1. Downhole The measurement takes place downhole. 2. Surface level The measurement takes place at surface level 3. Push in type The vane is pushed in, the measurement takes place at surface level This part of ISO 22476 specifies requirements for investigations of soil by the field vane test within the scope of the geotechnical investigations according to EN 1997-2. This part of ISO 22476 covers the field vane test used in cohesive soils for the determination of the undrained peak and remoulded shear strength and the sensitivity of the soil.
