| Abstract: | Dynamic compaction technique is adopted together with gravel ring beam base as the large tank foundation treatment method in complicated geological conditions in Abu Dhabi Crude Oil Project. Dynamic compaction trial and dynamic compaction schemes,construction of ring beam base and construction acceptance are illustrated in this paper. The dynamic compaction scheme is finalized based on the results of dynamic compaction trials and the finite element simulation calculation,and dynamic compaction is valued by pressure-meter test（PMT）,plate load test（PLT）and finite element simulation. PLT results and tank settlement reports show that the foundation treatment effect meets standard requirements. |
