国家对爆炸物控制的越来越严格,水电工程勘察的地震勘探震源受到了严重的制约,为此以机械冲击式震源为代表的非爆炸震源的研制工作成为业内人士的共识。机械冲击震源以其灵活轻便、非破坏性、信号信噪比高的特点已成为一种重要的炸药替代震源。文章对自行研制的冲击震源与锤击、落重等一系列非爆炸震源信号进行了比较,分析了各震源信号的特点,以供实际应用和研究参考。
The control of explosives in our country is more and more strict. The seismic source of hydro-prospecting has been severely restricted. Therefore, the research on non-explosive source represented by mechanical shock source has become the consensus in the industry. Mechanical shock source with its flexible and lightweight, non-destructive, high signal-to-noise ratio has become an important source of alternative explosives. In this paper, a series of non-explosive source signals such as impact source, hammering and falling weight developed by ourselves are compared and the characteristics of each source signal are analyzed for practical application and research reference.
