摘要: 无人机倾斜摄影技术凭借高精度、多视角还原真实地貌的能力,已在地形地貌测绘、城市三维建模、工程勘察建设、土地利用规划等领域得到了广泛的应用。本文采用无人机倾斜摄影+遥感综合解译+落石轨迹模拟的综合研究评价方法,基于西藏某新建公路两侧高陡边坡实景三维倾斜模型,对该区域发育的危岩体开展了详细的解译分析,共识别危岩体67处,通过稳定性及其对下方公路威胁性分析,得出危岩体对该区域西侧中部、北侧坡面东部及南侧坡脚部分区域具有明显威胁性,易对公路来往行人及车辆造成危害。研究成果为现场危岩体清理、防护治理提供了重要的技术依据,有效弥补了现场人员无法到达、勘察作业困难的缺陷,具有重要的理论及实际意义。

Abstract: Drone tilt photography technology, with its unique advantages of high precision and multi perspective restoration of real landforms, it has been widely applied in fields such as terrain and geomorphology surveying, urban 3D modeling, engineering survey and construction, and land use planning.This study adopts a comprehensive research evaluation method of “unmanned aerial vehicle oblique photography+remote sensing comprehensive interpretation+rockfall trajectory simulation”,based on the 3D slope model of high and steep slopes on both sides of a new highway in Xizang, a detailed interpretation analysis is conducted on the dangerous rock bodies developed in the region, identifying a total of 67 dangerous rock bodies. Through stability analysis and its threat to the road below, it indicates that the dangerous rock mass poses a significant threat to the western central part of the area, the eastern part of the northern slope, and some areas at the foot of the southern slope, which can easily pose a threat to pedestrians and vehicles traveling on the highway.The research results provide important technical basis for the cleaning and protection of hazardous rock masses on site, effectively compensating for the shortcomings of on-site personnels inability to reach and difficult survey operations, and have important theoretical and practical significance.

Key words: oblique photography, high and steep slopes, dangerous rock mass, comprehensive interpretation, stability evaluation
