Abstract
The principal purpose of the problem which forms the basis
of this study was to look int.o the possibility of providing a
rational analytical solutions for predicting the forces on a cutting
blade driven horizontally into a loose sand. However, such
analytical solution must be checked by a selected number of
experimental tests to verify their accuracy. In this study the
mathematical solution using a limit analysis theories based on
the relationship between the horizontal force and the direction
of movement for a given set of soil strength parameter’s and a
given plate configuration. The observation of soils under
conditions of failure often resent the basis for the development
of important theorems leading a solutions for forces and
deformations at failure. A glass-sided tank was designed to accomplish the
observation and phtographing of the total soil failure zone. A
series of experimental tests performed by using cutting blades
with different angles of inclination-rigidly attached to a carriage
and moved through a loose sand at specified constant speed and
various depths of cut. The purpose of the experimental
programme was to provide data on the interaction of the chosen
cutting blades embedded in frictional soil under plane strain
conditions which could be compared with anlaytical results.
Mainly the following facts were investigated.
