Research Of Attenuation Law Of Blasting Vibration And Vibration Response Spectrum Properties Motivated By Blasting Velocity

Blasting vibration caused by construction is inevitable to affect the structure in thesurrounding area, which needs control the hazards caused by blasting vibration of construction.Therefore, it is the basic premise that studying the laws of the blasting controls the harm ofblasting vibration. The paper makes the regression analysis for the peak particle velocity ofblasting vibration and proposes the experience formula of the peak velocity that based on themeasured data of blasting vibration. And according to the theory for response spectra at homeand abroad, we find mostly the case that using input the acceleration of blasting vibration tostudy the response of blasting vibration. The paper proposes the formula of response spectrum byinputting the velocity of blasting vibration to calculate the response spectrum and verify it. Andthen using the solution of linear convolution calculates the formula. At last through the softwareof MATLAB compiling the appropriate program to calculate the response spectra of acceleration,velocity and displacement by data of field measured. A summary on law of response of blastingvibration by the obtained curve of response spectrum and the research for the process of blastingvibration has important significance.
