| 摘 要： | 全波震相分析法是以弹性波传播理论为基础,以现代数字技术为手段,对地震波进行全面综合分析的理论和方法.它既包括对单一分量震波观测记录中的各种震相的识别、确认和分析,又包括对多分量震波记录的合成、分析和图示.全波震相分析法涉及震源、射线路径、初动、走时、振幅、波形、时域和空域的瞬态谱、质点振动矢量等诸多方面,因而能更全面地揭示地震波场与地下介质之间的关系.本文以实例展示在不同领域的研究中全波震相分析的应用情况.全波震相分析法为实现多种波型的联合应用奠定了理论基础,并提供了新的方法.

| Abstract: | Full wave phase analysis (FWPA) is based on the theory of elastic wave propagation and makes use of the up-to-date digit technique to analyze the seismic wave field wholly and synthetically. It involves not only distinguishing and analysing various phases in mono-component' seismic waves, but also those of in multiple-component seismic waves. FWPA deals with the various kinematic elements of the wave field and can more fully reveal the relationship between the seismic wave field and the propagating media. This paper shows the application of FWPA with actul examples. FWPA lays a theoretical basis and gives a new method for the really combined action of longitudinal and transverse waves as well as more complex wave patterns. |
