Abstract when a precise exploration technology was realized by a borehole-to-surface electrical prospecting as CT scans of medical images, the technological of the geoelectrical resistivity survey had progressed into a high phase of the comprehensive quantitative interpretation, more geological exploration projects have historically been hard problems to solve, they can be completed. The article describes a example of the precise geological exploration about successful application of the surface-to-borehole electrical resistivity tomography survey, when collapses of karstic geology were occured in the stage of construction, to ascertain complex karstic geologies at a short time, a low cost and high efficiency. so that survey results provides the reliable geological data for the disclosed hidden trouble of karst geologies, the designs of the treatments and the technology of karst foundation treatments.
