摘要
瑞雷波的频散特性是瑞雷波勘探工作的直接目标。根据瑞雷波在传播媒体中的速度以及与以波长为单位的转换深度给绘制频散曲线，由频散曲线拐点求取传播媒体物性界面的深度，再由频散曲线各段的速度变化梯度求取传播媒体中各层的瑞雷波层速度，并用统计规律换算各层的横波速度，进而完成各种工程目的的工程地质参数计算。介绍了大亚湾填海工程中工程地质勘测及高速公路勘测中瞬态瑞雷勘测实例，证实了瞬态瑞雷波法的实用性。
The dispersive charaeteristics of Rayleigh wave is the direct objective of Rayleigh wave ex-ploration.The dispersive curve can be obtaibed by the velocity of Rayleigh wave in media versus the con-verted depth in unit of wavelength.The interface depth of media devided by the physical properties canbe interpreted on the dispersive curve by the inflective point. The interval velocity of Rayleigh wave iscalculated by using the velocity gradient of each segmeut on the dispersive curve.The velocity oftransversal wave of each layer is calculated according thestatistic method. And finally, the engineeringqeoloqical parameters can be obtained for various engineering purposes.The applications of Rayleigh wave exploration in the engineering geological survey for sea fillingproject in Daya Bay and in the investigation of highway ave introduced as exampes to verify the usagesof kayleigh wave exploration
