現地爆破震動監測及能量衰減特性研究
Field monitoring and Analysis of blasting vibration
摘要
隨著人口的增長以及爆破技術的應用越來越廣泛。在隧道挖掘，道路開發及人工震源中所產生的振動也引起了人們的注意。在爆破作業的過程中，影響爆破震動的因素甚多，這也增加了控制爆破震動的困難。在工程爆破施工中所引起的振動對其周圍的建築、設施結構、邊坡和人員產生不同程度和範圍的影響。本研究分別以發爆炸藥量、現地地質地形與爆破震動等參數對最大質點振動速度之影響進行監測，透過實際現場爆破記錄與爆破震動量測記錄，配合岩石性質，探討爆破過程中振波能量傳遞及衰減特性。藉由開炸震動之最大質點振動速度，以瞭解爆破震動之傳遞及衰減程度。本研究分為5個爆序，分別測試在不同裝藥量及不同延遲時間引爆時間下所產生之爆破振動值。依據所量測振動值資料進行爆振波在岩石間傳播時之衰減特性研究，並以前蘇聯學者薩道夫斯基所提出之經驗公式計算爆破現地之爆破地層參數及振動值衰減參數，提供往後相關爆破工程之參考。

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.
