Behaviour of wet clay soil under single cage wheel lugs

Abstract

This paper presents the results of studies on the deformation of wet clay soil under the action of a single lug. The effect of lug angle on the soil deformation has been investigated. The experimental results are critically compared with the conventional theories of soil failure. It was observed that the existing passive soil pressure theory could not be used to describe soil movement caused by the action of the cage wheel lug. Speculation about the soil failure prediction due to a rigid tine or soil cutting blade has raised doubts about the wisdom of applying this theory to other soil cutting tools.
