The Fall Cone apparatus provides a rapid, simple and accurate method for determining the undrained shear strength and the sensitivity of both undisturbed and remoulded clays. The relationship between the depth of penetration of the fall cone and the undrained shear strength has been determined after many years of research. The equipment is also used for determination of liquid limits (fineness number).

In the new model, designed by the Norwegian Geotechnical Institute, the fall cone is suspended by a permanent magnet, and the testing capacity covers a range of shear strengths from 0.01 to  20 t/m2.

The test is fully discussed in “New Approach to the Determination of the Shear Strength of Clay by the Fall Cone Test” by Sven Hansbo. Proc. Royal Swedish Geotechnical Institute Nov. 14, 1957.
