APPLICATION OF DIGITAL IMAGING TECHNOLOGY OF BOREHOLE-WALL IN SEEPAGE CONTROL ENGINEERING OF THE ANCIENT TOMB

Digital imaging technology of borehole-wall may produce continuous 360° images of the boreholewall with high resolution and up to 100% borehole coverage, intuitive and convincible, from which geologic phenomena in the borehole can be qualitatively described and quantitatively analyzed.Digital imaging technology of borehole-wall with a wide range of applications, primarily for geotechnical engineering, oil industry, civil engineering, mining engineering, engineering geology and many other areas.Appling Digital imaging technology of borehole-wall to a tomb impermeable pilot projects, aided to survey tomb overlying rock broken, get rock crushing position, degree of fragmentation, fracture occurrence information, and analyze tomb leaking reasons, provide a scientific basis for the design and construction of impermeable grouting.
