dc.description.abstract | This thesis includes experimental and theoretical work
performed to investigate the behaviour of ground anchors
in sand. The anchor footing used was a circular plate
connected to a tie rod.
The experimental work was carried out by installing the
anchor in a l830mm x 1830mm x l220mm deep tank containing
dry sand. The sand sample was prepared by using a vibrator
fixed to the bottom of the tank. The anchor was pulled out
at a constant rate of strain and the load-displacement
curve was recorded on a plotter.
The vibration of the tank was defined by deter.mining the
acceleratton and amplitude of the motion in the horizontal
and vertical directions.
A density tube and a hydraulic gauge were designed to
investigate the distribution of stresses in sand.
The variation of the vibration time, the constant rate of
strain, theshafVplate diameter, the plate thickness/plate
diameter, and the boundary distance with the load-displacement
curve were also investigated.
The load-displacement curve of different diameter plates
embedded at various depths for different times of vibration
were recorded.
To investigate the behaviour of ground anchors theoretically,
the finite element technique was used and a computer progra~
developed.
A linear stress-strain relationship was used to predj.ct and
investigate the behaviour of the anchor.
A non-linear stress-strain relationship and a failure criterion
were also used to predict the load-displacement curve of the
vertical anchor. The effect of the parameters which were investigated
experimental:lll;;l.were.allso,examined. The distribution
of the load on the anchor plate and the extent of the failure
zone were plotted.
The predicted and experimental results in this thesis were
compared with laboratory and field results obtained by
previous researchers. | en_US |
