摘　　要：从数值模拟方法、理论研究和工程应用方面对软土地基动力固结理论进行的研究表明,在考虑排水条件下采用特殊工艺的强夯法能达到软基处理的预期效果。虽然研究已取得一些进展,但理论与实践之间仍有较大差距,例如加固机理、加固深度的计算及效果评价方面还没有统一认识,成果真正用于实践的还不多,微观效果的研究几乎为空白,这些问题成为今后的研究方向。Research on dynamic consolidation theory of soft soil foundation in respects of numerical simulation method, theory study and engineering application shows that expected effects can be achieved by specific dynamic compaction under dewatering condition. Though the research has made some progress, there is still quite difference between theory and practice, for example, no unified cognition reached in respects of consolidation mechanism, consolidation depth calculation and effect assessment, nor much of the research result really used in practice, and almost nothing done in micro-effect study. These issues will be the subjects of future research.
