碩士 === 國立臺北科技大學 === 資源工程研究所 === 101 === With the progress of blast technology , blast vibration become the most important topic when tunnel excavation.Blast vibration is hard to control because of many effects. Blast vibration during blasting would effect some construction, environment and slope stability in different range. The study use different charge and different blast vibration parameter to analysis the attenuation of blasting vibration .Use peak partical velocity to evaluating the degree of attenuation of blasting vibration. The procedure of this research is divided into five steps, which respectively measure the blasting vibration caused by detonation with different charges and delay times. The measured vibration is used to do the analysis of shockwave deterioration when propagating through rocks, using the empirical formulas proposed by former Soviet scholar Sadaovsk formula to calculate the blasting geological parameter and vibration deterioration parameter in the blasting site, as a reference for blasting engineering in the future.
