Ground investigation and testing - Field testing - Part 9: Field vane test prEN ISO 22476-9

Scope

This standard 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. 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.
