地震波研究

STUDIES ON SEISMIC WAVES

回顾了近 4年来中国地球物理学家在地震波研究方面取得的主要进展 .分别简要地讨论了层状均匀介质、横向不均匀介质和多孔介质中的地震波传播 ,地震面波及波形反演 ,以及地震勘探、测井问题中的地震波研究方面取得的新成果 .指出当前地震波研究的重要课题是发展高效的数值方法 ,并利用该方法开展复杂介质中的地震波激发和传播 ,以及强地面运动的研究 。

The development of seismic wave study in China in the past four years is reviewed. The discussion is divided into several aspects, including seismic wave propagation in laterally homogeneous media, laterally heterogeneous media, anisotropic and porous media, surface wave and seismic wave inversion, and seismic wave study in prospecting and logging problems. Important projects in the current studies on seismic wave is suggested as the development of high efficient numerical methods, and applying them to the studies of excitation and propagation of seismic waves in complex media and strong ground motion, which will form a foundation for refined earthquake hazard analysis and prediction.
