movement at the beginning. This is related to the assumption
that the heave of soil plug is caused by the penetration of
caisson walls. A fitting of the experimental curves using a value
of
m
=1.4 was also made. m=1.4 implies that the volume of the
soil going into the caisson cavity was 140% of the volume of
the soil replaced. This is possible as the additional 40% could
come from the expansion of the remolded soil or flow of soil
beneath the caisson. As discussed before, the soil plug was
broken at the end of the experiments. This aspect could not be
modeled by the analytical method.

5 CONCLUSIONS
Suction caissons have been used mainly as foundations to
support offshore structures in deep water. Their applications in
shallow water are more challenging as the amount of suction
that can be applied to install the caissons is much less. Several
model tests on the use of suction caisson in clay in shallow
water were carried out. The height of soil plug, displacement of
the suction caisson and applied vacuum pressure were measured
during the model tests. An analytical method proposed by
Houlsby and Byrne (2005b) were adopted to simulate the model
test results. The analytical results agree well with the model test
results with the selection of appropriate parameters.
