By taking a three-freedom elastic structure under two-dimensional blasting seismic waves as investigating subject,this paper developed a solution to getting its dynamic responses with the use of time history analysis method which was assisted by Matlab programming.Based on analyzing the results of peak values of structural dynamic responses under different conditions,effects of three blasting vibration factors including peak value,frequency and duration on the dynamic response of a three-freedom elastic structure to two-dimensional blasting seismic waves,were discussed and several useful outcomes were presented.The present paper offered references to the establishment of multi-parameter safety criterion for multi-dimensional blasting seismic waves.
