Abstract
An oil storage tank at the North suburb La Goulette (Tunisia) was founded on reinforced soft soil by floating sand columns of 6 m in length and 11% of improvement area ratio within a thick compressible clayey soil. Serious contamination of tank due to very significant differential settlement forces the decision to terminate its operations. Reinforcement by inclined rigid inclusions was suggested to neutralize the evolution of consolidation settlement in sub compressible clay layers. Numerical predictions were implemented for the study of the post behavior of tank on reinforced soil by rigid inclusions. Effectiveness of solution using inclined rigid inclusions is illustrated and, then, discussed. Modeling of the contact between the rigid inclusions, by means of element of interfaces, and soft clay has been seen of great importance when predicting the evolution of long term settlement.

Soil Reinforcement by Rigid Inclusions: Contamination of an Oil Storage Tank
Chicago, Illinois
An oil storage tank at the North suburb La Goulette (Tunisia) was founded on reinforced soft soil by floating sand columns of 6 m in length and 11% of improvement area ratio within a thick compressible clayey soil.
