Based on the geological conditions of the site, the composite foundation with rigid piles was selected for the foundation of 50,000m3 steel oil container. Given that there are not suitable regulations in the existing codes for the issue above, the Code for Soil Improvement (JGJ79-91) is referred to. By calculating and site testing of the piles, the pile diametre, interval space, grade of the strength of concrete are given. 1467 piles are employed in each foundation. By the low strain test, the percentage of first-rate is more than 83% among the tested piles. Hitherto, the foundation of the container keeps stability. For the soil improvement of giant steel oil container, the composite foundation with rigid pile shows such advantages as lower investment, reliable technique, better economical and environmental benifit.
