本文首先把野外常规地震勘探方法中的柱状炸药震源简化为连续的线状震源进行分析,指出其所存在的问题。然后给出一种新型的组合延迟爆炸震源,并运用声波的多普勒效应和付里叶波谱分析法研究新震源的响应特性。理论结果表明,它不但是一种能产生高频和高信噪比的可靠的炸药震源,而且还可以使地震波穿透深部地层,压制虚反射。本文还给出新震源的特征波形的实验室测试方法。 In this paper, firstly, the source of column explosives in conventional field seismic exploration method is simplified into continuous linear source, and its existing problems are pointed out. Then, a new combined delay detonation source is given, and the response characteristics of the new source are studied by Doppler effect of acoustic wave and Fourier spectrum analysis. Theoretical results show that it is not only a reliable source of explosives that can generate high frequency and high signal-to-noise ratio, but also can make seismic waves penetrate deeper strata and suppress the reflections. In this paper, we also give a laboratory test method for the characteristic waveform of a new seismic source.
