摘　　要：目前,强夯法已经广泛用于处理各种地(路)基,但是能否用来处理饱和淤泥质软土仍存在争议。结合某淤泥质软土路基,通过分析路基中孔隙水压力的消散、路基的沉降以及路基处理前后一些关键指标的变化,认为在该条件下,用强夯法来处理该软土路基是可行的,该路基经过处理后的各项指标均满足设计部门的要求。并得到了一些有用的结论,可以被其它类似的工程所借鉴。At present, Dynamic Consolidation Method has been applied to treat all kinds of roadbed or foundation frequently, but it is still questionable whether such a method can be applied to consolidate saturated and silty soft roadbed. In this paper, combined a silty soft roadbed, the changes of some key indexes including the dissipation of pore water pressure, the sedimentation of the soft roadbed and others have been analysed before and after the consolidation of the roadbed. In this case, it is feasi ble for the dynamic consolidation to treat the soft roadbed, after the consolidation the indexes can meet with the requirement of the design. It may also to be useful as reference to some other similar projects.
