全孔壁数字成像技术在古墓防渗工程中的应用

Application of Digital Imaging Technology of Borehole-wall in seepage control engineering of the ancient tomb

全孔壁数字成像技术可以从侧视视角对整个钻孔的360°孔壁进行连续摄像,通过图像特征对孔内地质现象进行定性描述和定量分析,具有高分辨率、高井壁覆盖率和直观可信等特征。将全孔壁数字成像系统应用到某古墓防渗试验工程中,辅助勘察墓室上覆岩体的破碎情况,获取岩体破碎位置、破碎程度、裂隙产状等信息,分析墓室漏水原因,为防渗注浆设计及施工提供科学依据。

Digital imaging technology of borehole wall may produce continuous 360° images of the borehole- wall with high resolution and up to 100% borehole coverage, intuitive and convincible, from which geologic phenomena in the borchole 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.
