摘要: 高陡边坡地带的落石灾害因其突发性强、破坏性大，已成为公共安全的重要隐患。为提升灾害防治效能，本研究创新性地运用无人机贴近摄影测量方法，针对黄河大桥左岸危岩体展开综合调查。通过融合现场实测数据与数字三维场景重构技术，精确揭示了危岩体的空间展布及结构面发育特征，为稳定性评价提供了数据支撑。建立包含离散裂隙的数值计算模型分析边坡稳定性，最后模拟失稳岩体的运动轨迹。本研究为高陡边坡的调查分析提供一个新思路，对防灾减灾有积极意义。
Abstract: Rockfall disasters in high and steep slope areas, due to their suddenness and destructiveness, have become an important hidden danger to public safety. To enhance the efficiency of disaster prevention and control, this study innovatively employed the unmanned aerial vehicle (UAV) close-range photogrammetry method to conduct a comprehensive investigation of the dangerous rock mass on the left bank of the Yellow River Bridge. By integrating on-site measured data with digital 3D scene reconstruction technology, the spatial distribution and structural plane development characteristics of the dangerous rock mass were precisely revealed, providing data support for stability evaluation. Establish a numerical calculation model including discrete fractures to analyze the stability of the slope, and finally simulate the movement trajectory of the unstable rock mass. This paper provides a new idea for the investigation of high and steep slopes, which is of positive significance for the research of disaster reduction technology and the governance of dangerous rock masses.
