摘要: 岩溶对于目前的工程建设是一个很大的隐患。本文介绍了井间地震层析成像的原理及工作方法,简要地阐述了地震波的反演理论基础。并利用层析成像反演软件对其在工区里获得的原始数据进行反演处理,对得到不同测线的反演剖面图进行解释。通过这一工程实例的应用效果,说明井间地震CT技术在圈定岩溶勘察中具有较高的精度和可信度,为工程设计提供了可靠的依据。

Abstract: Karst for the engineering construction is a very big hidden trouble.This paper introduces the principle and working method of the cross-well seismic tomographic imaging,and then briefly introduced the seismic inversion theory foundation.Finally,by using tomography inversion software in the work area to get original data inversion processing,get different line of inversion profile to explain.Through the project example application result shows that crosswell seismic CT technology in karst exploration has higher precision and reliability,for engineering design and provides the reliable basis.
