| Abstract: | Ultra|deep and ultra|long cement stirring piles were adopted in strengthening the foundation of a 50000m 3 large oil tank. To guarantee construction quality, engineers selected and determined the stirring machines and construction methods. Problems were found in the analysis of testing piles, testing pile methods were analyzed and calibrated consequently, and construction method was improved finally in practical construction. In this article, the author emphasizes the optimization of time|control of formation of a single pile, controlling cement portion and adjustment of the stirring method. |
