| 摘 要： | 本次研究选取北京房山区一处典型崩塌隐患点,采用倾斜摄影测量技术获取了研究区三维实景模型,圈定了危岩体及受威胁对象,开展了崩塌隐患的稳定性分析,模拟了典型危岩体发生崩落后的运动轨迹。研究成果表明倾斜摄影技术能够获取崩塌灾害隐患的地形地貌、岩性构造、几何形态等特征信息,可以为崩塌灾害隐患的勘查、防治工作提供参考依据。

| Abstract: | A typical potential collapse site in Fangshan district,Beijing is selected for research.The real-time 3D model of the potential collapse site is obtained by oblique photography.Then the landform,lithology and structure of the study area are analyzed.The dangerous rock mass and the threatened object were delineate,the track of the typical dangerous rock mass were analyzed.The results show that the oblique photography can obtain the landform,lithology,structure,geometric form and other information of the collapse hazard.It can provide reference for the exploration and prevention of potential collapse hazards. |
