【摘要】 在面波勘探中,随着软件和硬件的发展及面波勘探技术理论的进一步完善,瞬态瑞雷波法越来越引起人们的重视。由于面波勘探与常规的地震勘探相比具有现场场地要求不高、快速经济、易于激发和识别、有效信号能量强、不受各地层速度的影响、对浅部地层分辨率高等特点,使得面波勘探技术被广泛地应用于探查地下介质结构并进行地层划分、海堤中软弱夹层的探测、天然地基剪切波速度测试、判定场地类别和评估软弱地基处理等无损检测工程领域中。本文叙述了瑞雷面波的勘探原理以及资料整理解释方法,并通过应用实例说明其在工程中的应用效果。更多还原

【Abstract】 With the development of software,hardware and the technical theory in the surface wave exploration,transient state raleigh wave method has become more and more important in engineering prospecting.Compared with genial surface wave method,the transient state surface wave has some prominent advantages,such as spending less time and money,exploding and identifying easily,strong useful signal energy,high resolution in the shallow layer.The method don’t need very fine work field and don’t be affected by formation velocity.Because of so much advantages mentioned above,transient state rayleigh wave method has been widely used in detecting the structure of the underground layer and stratigraphic division,detection of weak intercalation in the seawall,natural ground shear wave velocity testing,determine work site classification and evaluation of soft ground and other nondestructive examination engineering.In the paper,we have depicted theory of raleigh surface wave exploration and technique for data processing and interpretion. We have also applied the method in the real engineering to explain its practical effection.更多还原
