摘　　要：针对传统高位危岩体地面调查强度大、效率低、风险高、精度低、轻整体重局部的不足,提出了基于无人机倾斜摄影技术的高位危岩体调查方法。本文以青城山后山景区危岩为例,通过无人机倾斜摄影处理技术流程,构建危岩体三维立体实景模型,通过解译分析,提取了危岩体地层岩性、产状、裂隙发育情况、块体大小等信息。结果表明,与传统地面调查分析相比,该方法更全面、客观、准确,具有巨大的推广前景。An investigation method of high unstable rock mass based on UAV tilt photography technology overcomes such shortcomings of the traditional ground survey as high intensity,low efficiency,high risk,low accuracy,neglecting the whole and attaching importance to the part.By the example of the unstable rock mass of the Qingcheng Mountain Houshan scenic area,this study establishes a three-dimensional scene model of the unstable rock mass by means of the UAV tilt photography technology,extracting information of stratigraphic lithology,occurrence,fracture development and block size of the unstable rock mass.The results show that this method is more comprehensive,objective and accurate than the traditional ground survey,and has a great prospect of popularization.
