摘要
人工地震是研究深部构造的重要方法之一。本文首先对我国地壳上地幔深地震探測的进展及展望做了概述。然后对人工地震测深技术,观测仪器,数据采集系统,资料处理及反演方法的发展,以及地壳速度结构特征,莫霍界面的性质、形态和地壳厚度,深大断裂特征和展布等方面的重大成果做了详细论述。最后提出了今后的展望。
Man-made earthquake is one of the important methods to investigate deep crustal tectonics. First, the progress and prospect in deep seismic sounding (DSS) of the crust and upper-mantle in China are outlined in this paper. Then, the great developments in exploring technique of DSS, observation instrumentation, data collection system, methods of data processing and inversing, as well as the major results concerning the characteristics of the crustal velocity structure, the features and shape of the Moho discontinuity, crustal thickness, properties and distribution of deep great ruptures are also discussed in detail. Finally, the paper points out the prospects of DSS in the future.
