| 摘 要： | 以蓉遵高速公路K338+850上行线危岩带为背景，介绍了基于无人机倾斜摄影的公路高陡危岩体调查评价方法。采用无人机倾斜摄影技术获取带有坐标信息的高分辨率图像，基于SFM法合成三维高清实景模型，利用最小二乘法进行平面拟合提取坡面岩体结构特征，明确调查区7处危岩体特征。在此基础上，运用Rockfall软件对危岩体的运动路径及运动特征进行分析，研究高陡危岩崩塌对公路的危险性，采用赤平投影和定量分析方法对危岩体的稳定性进行评价。

Parameter Acquisition and Stability Evaluation of High and Steep Dangerous Rock Mass Based on UAV |
| |
| Abstract: | Taking the rocky belt of Rongzun Expressway K338+850 ascending road as the engineering background, an investigation and evaluation method of high and steep dangerous rock mass of road based on UAV tilt photography is introduced. UAV tilt photography technology was used to obtain high-resolution images with coordinate information, 3D hd real scene model was synthesized based on SFM method, and plane fitting was used to extract structural features of slope rock mass using least square method and define 7 dangerous rock mass characteristics in the investigation area, on which basis, the motion path and motion characteristics of the dangerous rock mass was analyzed by using Rockfall software, so as to study the high and steep dangerous rock collapse on highway. The stability of dangerous rock mass was evaluated by using stereographic projection and the quantitative analysis method. |
