Abstract：Blasting does work using explosion energy. It is a cheap and economical means of rock and soil excavation and widely used in ground and underground excavating engineering projects. Blast-induced ground vibration has harmful impactes on nearby structures and fields. The peak particle vibration velocity produced by ground vibration is commonly used to evaluate the risk of blast earthquake. There have been some empirical equations and methods to predict the peak ground vibration velocity; however, these equations are invalid under the situation that specific conditions used for deduction can’t be met. When blast earthquake wave propagates in rock and soil masses, ground vibration is complex and is influenced by mumerous parameters. The paper made a discussion about the empirical equations and Fourmap method of predicting the peak ground vibration velocity due to blasting. What is more, an attempt has been made to predict the peak ground vibration velocity in blast earthquake by using an artificial neural network.
