Abstract

Abstract

Using the complicated cavities as an example,the paper discussed the comprehensive electrical method of electrical sounding and electromagnetic CT after considering the comprehensive factors.During the study,data were acquired twice before and after the grouting,respectively.The test study results and the field borehole data proved that the combined method can reflect the grouting quality of cavities in detail simply and efficiently.It also proved that the comprehensive method is reasonable,effe...
