Abstract:

To investigate the dynamic compaction mechanism of loess-filled embankment, a computational model of unit volume compaction effort was proposed as compared with the compaction test. The energy level of dynamic compaction used in actual projects was also considered. The differences between the compaction test and the unit volume compaction effort in the actual projects were studied. And also, the unit volume compaction efforts of the main tamping point and the whole reinforcement scope were analyzed. It can be drawn out that the compaction criterion should be chosen based on the water content of loess on site. Based on the model test, the laws of acceleration, velocity and displacement under the dynamic impact of hammer on the loess-filled embankment were analyzed in our study. The whole process also perfectly explained the movement history of hammer under dynamic compaction and the work-energy conversion efficiency of dynamic compaction.
