摘要
介绍了综合运用多偏移距地震映像法与瞬态瑞雷波法对隧道底部隐伏岩溶探测的工作方法与主要技术,通过对偏移距地研究,分别论述了多偏移距地震映像法、瞬态瑞雷波法的基本原理和数据处理流程,以及这两种方法勘探效果的互补性。通过对实际隧道进行综合应用的实例以及最终钻孔验证,说明了多偏移距地震映像法与瞬态瑞雷波法对隧道底部隐伏岩溶探测的有效性,在勘查工作中,提供更加充分的解释依据,提高工作效率以及地质解释工作的准确性。
This paper introduces the integrated use of more than offset seismic image method and the transient Rayleigh wave on the bottom of the tunnel karst detection method and main technical work,through the study to offset,respectively discusses the offset seismic image method and the basic principle of transient Rayleigh wave and data processing flow,and the exploration effect of complementarity of the two methods.Based on the comprehensive application instance of the actual tunnel and the final drilling verification,illustrates how offset seismic image method and the transient Rayleigh wave on the effectiveness of the concealed karst cave at the bottom of the tunnel,in the exploration,provide more fully explain the basis,improve work efficiency and the accuracy of geological interpretation work.
