Experimental study on vibration transferring of dynamic compaction for foundation ground by hydraulic filling

Dynamic compaction is a well known and effective method in ground improvement. The application of this method is often restricted because of its noise, vibration and construction environment. Subject of dynamic compaction is very complicated, it is impossible to establish general theory for all classes of foundation. Vibration transferring of dynamic compaction and choice of damage indexes are discussed. Attenuation characteristics of vibration by dynamic compaction are studied by field detection in dynamic engineering of CaoFeiDian industrial park. In the meantime, puts forwards the experience formula of attenuation of acceleration. The conclusions of this paper may be useful for application in dynamic compaction construction.
