【Abstract】 Based on the dimensional analysis method,the function relations among all the physical quantities those impact the blasting vibration frequency are establish,and then the regression analysis is made in combination with the actual measured blasting vibration data from the construction of Pubugou Hydropower Station.Furthermore,the law of the vibration frequency is discussed under the conditions of both the shallow hole blasting and deep hole blasting,with which the prediction formula for the blasting vibration frequencies under the particular conditions is established;which provides a theoretical and practical basis for the study on the attenuation law of the blasting vibration frequency and the prediction of the principal frequency concerned for the similar projects.更多还原
