主 题：Blasting vibration Wave component Field blasting tests Attenuation equation Uncertainty analysis Bayesian theory
摘 要：A typical blasting vibration wave is a composite wave,and its attenuation law is affected by the type of dominant wave *** purpose of the present study is to establish an attenuation equation of the peak particle velocity(PPV),taking into account the attenuation characteristics of P-,S-and R-waves in the blasting vibration *** blasting tests were carried out as a case to specifically apply the proposed *** view of the fact that the discrete properties of rock mass will inevitably cause the uncertainty of blasting vibration,we also carried out a probability analysis of PPV uncertainty,and introduced the concept of reliability to evaluate blasting *** results showed that the established attenuation equation had a higher prediction accuracy,and can be considered as a promising equation implemented on more complex *** adopted uncertainty analysis method can comprehensively take account of the attenuation law of blasting vibration measured on site and discrete properties of rock *** obtained distribution of the PPV uncertainty factor can quantitatively evaluate the reliability of blasting vibration,which is a powerful and necessary supplement to the PPV attenuation equation.
