摘　　要：三峡链子崖危岩体防治工程之前进行了大量的调查和勘探工作,为开展整治工程奠定了基础,其中物探技术发挥了重要作用。本文简要介绍了音频大地电场法、甚低频电磁法、电测深法、高密度电阻率法、浅层地震法、声波跨孔法等物探技术探测隐伏裂缝、煤洞、岩溶以及堆积物厚度等方面的应用成果和一些经验。Lots of investigation and survey have been done before carrying out the controlling project of Lianzi Cliff dangerous rockmass. These work provide the basis for studying the remedial scheme, especially, the geophysical prospecting plays an important role. This paper introduces the application results and some experience for detecting invisible crack, coalhole, karst and the thickness of accumulation by using audio frequency electric method, VLF electromagnetic method, electric sounding method, high density resistivity method, shallow seismic method and sound wave cross hole method.
