摘　　要：为高效准确识别、研究岩质陡坡危石崩塌地质灾害,采用倾斜摄影测量、三维建模、遥感解译技术,通过无人机倾斜摄影测量,采集广州市番禺莲花山裸露的高陡边坡航摄数据,利用测量数据建立高分辨率实景三维模型,可快速识别裸露危岩体,提取岩质陡坡危石的结构面,分析和评价裸露的危岩体稳定性和变形发展趋势。研究表明,岩质陡坡危石一般发生在节理裂隙发育的坚硬岩石组成的陡峻山坡与峡谷陡岸上,应采取主动加被动防治技术措施,尽可能降低或消除危石崩塌风险。In order to efficiently and accurately identify and study the geological hazards of rock and steep slope collapse,oblique photogrammetry,3D modeling,and remote sensing interpretation technology are adopted.Through unmanned aerial vehicle oblique photogrammetry,aerial photography data of the exposed high and steep slope of Lianhua Mountain in Panyu,Guangzhou is collected.Using the measurement data,a high-resolution real-life 3D model is established,which can quickly identify the exposed dangerous rock mass,extract the structural planes of rock and steep slope collapse,analyze and evaluate the stability and deformation development trend of the exposed dangerous rock body.Research has shown that rocky steep slopes and dangerous rocks generally occur on steep slopes and steep banks of canyons composed of hard rocks with developed joints and fissures.Active and passive prevention and control measures should be taken to minimize or eliminate the risk of rock collapse as much as possible.
