Abstract
Based on the model, field test and theory research, this paper puts forward the design method of ground vibration isolated by silo and pita barriers, the practical engineering calculation and the remained problems in this respect. It is pointed out that although the diameter of pile is much smaller than that L/δ shielded wave length (Woods 1978), the ground wave motion can be effectively shielded so long as the proper pile distance is to be selected. This makes it possible that the silo and pile (as well as the pile of other form and material) barriers can be used in practical engineering. A successful example of silo and pile barrier engineering is firstly reported. The paper also established some design specifications as "Transmission effect" - efficiency of vibration isolation; "Diffraction effect" - range of vibration isolation; and "Coincident effect'' - result of vibration isolation. The author’s view on the relationship between the wave length and the depth and length of near fielded barrier (active vibration isolation) and far field barrier (passive vibration isolation) is also presented.
