摘要
Taking a structure of single-degree freedom as analyzed object, the problem of structural dynamic response to blasting vibration loads was transformed into the problem of that to a series of simple harmonic loads with wavelet packet method. A safety criterion of structural response to blasting vibration has been put forward, which is more detailed, reasonable and scientific than others in use with involving parameters related to structural characteristics, blasting energy, blasting amplitude, blasting frequency and blasting duration.
