Centrifuge model test for high embankment deformation control using dynamic compaction technique

Based on the similar theory of model test,a group of centrifuge model tests are carried out to investigate the deformation and settlement of high embankment of an airport treated with dynamic compaction technique.The effect of dynamic compaction combined with site test is evaluated.The research result shows that the high embankment without being treated with dynamic compaction can't satisfy the needs of engineering design owing to the oversize height of fill soil,whereas the fill soil with dynamic compaction can accomplish the settlement fast after construction,including instant settlement and consolidation settlement,and the deformation and settlement are controlled.It is proved that the dynamic compaction technique is fit for reinforcing treatment of high embankment in mountainous areas,and can control the uneven settlement of high embankment.
