摘　　要：针对高陡边坡稳定性问题,以乌东德水电站为例,借助Adam三维数码照相技术在地质编录的独特优势,结合三维块体稳定性分析技术,建立了一套高陡岩质边坡块体稳定性研究的系统方法,并与传统方法进行了比较。结果表明,该方法可确定块体发育位置、特征、规模及稳定性,且高效、准确、安全,为工程设计与施工提供了重要依据。Aiming at the stability problem of high steep rocky slope, on the basis of the advantages of Adam three-di- mensional digital photography technology in geological recording, the systematic method for studying on high steep rocky slope stability is established by combining with three-dimensional block stability analysis technology. And then it is ap- plied to Wudongde hydropower station. Compared with traditional method, the results show that the proposed method can not only determine block development position, character, scale and stability, but also has advantages such as high ef- ficiency, accuracy and safety. Thus, it provides important basis for engineering design and construction.
