14.05 Field Inspection Vane Tester
The shear strength or stress of the soil depends on different soil characteristics such as for instance: the granular composition, the humus content, the humidity and (in case of vegetation covered areas) the degree of coverage and the density of the roots. In order to determine the shear stress in the strata in for instance a profile pit, on the surface (for instance a sports terrain), at the bottom of a borehole or in a sample, several different shear stress meters have been developed.
