摘要：Dynamic consolidation has been widely used in many engineering fields. But in the use of discarded iron slag filled embankment, because the discarded iron slag is naturally piled up, multi-size particle mixture and backfilling height is relatively high, the effect of simple dynamic compaction is not obvious. This paper, combined with engineering examples, through the dynamic consolidation test, describes the experimental program, arrangement and spacing of tamping point, and matters need to be taken care in construction. It also explains the horizontal effects in consolidation by detection data analysis of waste iron slag roadbed. In this paper, we have established finite element numerical simulation analysis of dynamic consolidation by using FLAC3D. It is available in roadbed practical application and can be reference in similar projects of dynamic consolidation.
