瑞利面波勘探在坝体隐患探测中的应用研究
|
摘要
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 kind of method in geophysical exploration with so many advantages,such as simple,rapid,economical,high resolution and so on.The method has been applied and achieved a good result in many fields.Rayleigh surface wave exploration is a kind of infrasonic wave with lower frequency and strong energy,and it is generated by the interface of medium and the energy will be decayed when the distance is increased.The Rayleigh wave has the geological information contained in underground medium like reflection and refraction wave.This paper introduces the Rayleigh’s concept,operating principle and method,dispersive characteristics,inversion study and practical data application and uses multi-channel detector measurements to know the application of the surface wave exploration to the hidden trouble detection of dams.
