摘要：

The influence factors and the general research situation, of blasting vibration to structures are elucidated briefly. The blasting vibration was monitored on site. Using the data from the monitoring of blasting ground vibration, the response spectrum of velocity, acceleration and displacement are fitted out by a FEM (Finite Element Method code named NDFEPS-2D). These spectrum are analyzed and compared. Influence of the ground parameters such as the clay or inclusion liquefaction interlayer on response spectrum are discussed. The displacement spectrum, the velocity spectrum and the acceleration spectrum can be used as design criteria in the dynamic response analysis of the structures. The method provides an effective tool for studying blast seismic effect, specially, for constituting velocity-frequency criteria.
