Abstract:Engineering blasting will produce a strong ground vibration,which may affect damage on structure, it’s necessary to predict the intensity of vibration.Based on 42 groups of blasting data,the three different methods (the empirical formula method,the function regression method and neural network method) are presented to forecast the intensity of vibration. the function regression method is more effective than the empirical formula method, the neural network method can predict three direction velocity peak values of blasting wave,It is pointed out that the precision of neural network method is the best. the neural network method can solve the many-parameter problem by the way of modifying the input variable. which submits efficient path to predict the intensity of vibration.
