Wet clay soil behaviour under multiple cage wheel lugs

Abstract

This paper presents the results of studies on the deformation of wet clay soil under the action of multiple lugs. The effect of trench spacing (the distance between trenches cut by successive lugs), lug slip and lug spacing on the soil deformation under cage wheel lugs was studies. Wedge formation under a succeeding lug has also been studied. It was observed that the soil behaviour under multiple cage wheel lugs was significantly affected by lug spacing and slip. The soil wedge formation as well as soil adhering to the succeeding lug was a strong function of lug slip and spacing. In all cases the soil deformation pattern was quite different from that caused by a single lug.
