本研究主要討論以爆竹震源做?淺層震源的問題。經比較三種不同震源在雜波測試中之結果,我們發現爆竹震源具有許多優越的特性,包括能產生高頻信號、效率高、容易攜帶、價廉及安全。尤其重要的,爆竹震源很容易製造,使用也在法律許可的範圍內。 爆竹震源可視?一種小型炸藥。本文中,我們將詳細介紹此震源之設計及操作程序。並且討論其特性限制,以做?使用時的參考。爆竹震源是一極佳的震源,不管反射或折射震測,都可加以應用。
We have designed a tool that uses firecrackers as the source for shallow seismic study. The performance of this instrument was evaluated by conducting noise test experiments comparing three different sources, at the NCU campus. Adequate high frequency, high quality signals were generated. Except for a slightly lower energy level, the firecracker source has many interesting features as distinct from other sources. It was found to be able to produce signals of high frequency and to be efficient, portable, cheap and safe. Especially, as firecrackers are obtained easily from local stores, the utilization of a firecracker source may circumvent complex government regulations and open opportunities for further development. All these benefits make the firecracker a convenient source worth introducing to the scientists in this country who are interested in the shallow seismic methods. The firecracker is an explosive with a very small charge. In this paper, we will describe the detailed designation and operation procedures for this new tool and also examine its properties and application limitations. Finally, a CDP seismic section is presented as a demonstration. If the background noise is not too high, the firecracker will be a useful source for shallow seismic surveys including both the reflection and the refraction methods.
