瑞利面波勘探是近年发展起来的一种新的浅层地球物理勘探方法,具有简便、快速、经济、分辨率高、成果直观、适用场地小等优点,已在许多领域得到应用,并取得了良好的应用效果。瑞利面波是一类频率较低、能量较强的次生波,主要沿着介质的分界面传播,其能量随着与界面距离的增加迅速衰减。瑞利面波与反射波、折射波一样都含有地下介质的地质信息。本文介绍了瑞利面波的概念、工作原理及方法、频散特征、反演研究以及实际资料的应用等方面,用多道检波器测量来了解面波勘探在坝体隐患探测中的应用。
Rayleigh surface wave exploration is a new shallow geophysical prospecting method developed in recent years. It has many advantages, such as simple, fast, economical, high resolution, intuitionistic result and small applicable field. It has been applied in many fields and obtained A good application effect. Rayleigh wave is a kind of low frequency, high energy secondary wave, which mainly propagates along the interface of the medium and its energy decays rapidly with the increase of the distance from the interface. Rayleigh surface waves and reflected waves, refracted waves contain the geological information of the underground medium. This paper introduces the concept, working principle and method of Rayleigh wave, dispersion characteristic, inversion research and the application of actual data. It uses multichannel geophone to understand the application of surface wave exploration in the detection of hidden danger of dam.
