Abstract: This article takes a dene field formed by wind force in the southwest of the Inner Mongolia Autonomous Region as an example.It expatiates that how to design and construct project using high energy level dynamic compaction to deal with large area hydraulic fill sand ground,and exploit many kinds of field test methods,such as plate loading test,static come penetration test,dynamic cone penetration,to detect and analyse reinforcement effect.It summarizes a suit of experience and methods to dispose hydraulic fill sand ground,which can be refered for similar ground consolidation and detection.
