摘要
瑞雷波常称为面波。瑞雷面波勘探方法是一种新型的地球物理勘探方法,是近期发展起来的一种浅层工程地球物理新方法。瑞雷面波勘探法最基本的理论是其频散特性。当介质为半无限弹性介质时,在自由空间和弹性介质分界面上将会出现一种波,这就是瑞雷波。面波勘探法主要有稳态法和瞬态法,两种勘探方法的区别在于震源不同,前者是以一单频率的瑞雷波来获取速度曲线,而后者需要分析叠加在一起的瑞雷波。两种方法最后得到的结果相同,但实现的技术路径截然不同,表现出各自的特点。
Rayleigh wave is often called the surface wave. The surface wave exploration method is a new type of geophysical exploration method. The shallow geophysics is a new method developed recently. The most basic theory of the method is its dispersion character- istics. When the medium is semi--infinite elastic medium, in free space and flexibility on the interface, a wave will appear, which is Rayleigh wave. Surface wave exploration method mainly refers to steady--state method and transient method. two methods lies in their different sources. The former is a sing Rayleigh wave speed curve, while the latter needs to analyze waves. The final results of the two methods are the same, but th different. e difference between the le frequency to obtain the the overlaying Rayleigh e technical paths are quite different.
