| Abstract | Ground improvement using stone columns were used for the construction of the tank
foundations for the Saudi Kayan Petrochemical Complex, Jubail, Saudi Arabia in three
different areas. This study uses a software DC-Vibro based on Priebe's Method and
PLAXIS-2D finite element program and calibrated with the results of a full scale hydroload
test to estimate the settlement of the tank foundations. The computed settlement
was higher than the measured settlements which attributed the fact that during the
installation of stone columns, rapid consolidation has already took place. This effect
was not considered in the design. The measured settlements were found to vary from 20
to 40 mm.
After using the finite element model to study the behavior of stone column, it was
concluded that generally 60-70 percent of the settlement occurred immediately during
the construction of tank foundation. The total anticipated settlement is usually
dependent on the tank diameter, applied load and subsurface stratigraphy. The
improvement of the cohesive soil is found to be higher than the improvement ratio for
cohesionless soil based on the field hydro-test settlement data. The field measurements
together with the analytical analysis as well as the numerical simulations of the tank
foundation showed good agreement after adjusted parameters. |
