摘要

层析成像是近年来得到蓬勃发展的一项无损检测新技术，具有信息量丰富、准确、直观的独特优势，因此，在土石坝无损检测中正发挥着越来越重要的作用。在阐述电阻率层析成像基本理论的基础上，对龙凤山水库土石坝进行一系列层析成像无损检测，查明了龙凤山水库土石坝的渗漏通道，同时也证实了利用这一方法进行土石坝无损检测的可靠性。现场试验表明，层析成像无损检测技术可以在土石坝的病害检测中推广应用。

Abstract

The tomography is a new nondestructive detection technique developed in recent years; it has special advantages of rich information

accuracy and visibility. So it has been playing more and more important role in detecting hidden danger of earth-rock dams. Based on the discussion of the theory of electrical resistivity tomography

a series of resistivity tomography nondestructive detcction tests has been carried out in Longfengshan Reservoir Dam. The seepage channels in Longfengshan Reservoir Dam has been found out; meanwhile

it has been approved that this method is reliable via applied to nondestructive detection in earth dams. The local tests indicate that the resistivity tomography nondestructive detection technique may be applied to detecting hidden dangers of earth-rock dams.
