For marine works with very thick foundation beds,compaction by blasting is one of newly developed compaction methods in recent years to consolidate the foundation beds.

Taking the construction of a riverbank subgrade as an example, this paper introduces the principles and construction technique of dynamic compaction, and detects the effect of dynamic compaction.

Numerical simulation of collapsible loess foundation reinforced by dynamic consolidation technique;

Reinforcement of soft soil foundation with hydraulic fill sand based on the method combined with dynamic consolidation and vacuum drainage;

After the dynamic consolidation the foundation of the one-storied workshop, Xianfan Automobile Factory, has attained the design demand in bearing capacity.
