摘　　要：针对目前泥石流灾害防治工作中存在的流域调查效率低、轻整体及重局部的问题,结合渭源寺沟泥石流治理工程实例,利用3Dmax软件和无人机倾斜摄影相结合方法,绘出泥石流灾害调查流域内拟布设工程三维数据模型和调查区航测组合图,其能够反映出治理工程和周围地形情况及二者间关系,为泥石流灾害治理工程的精确设计和施工提供了可靠依据;基于依托工程实例,提出了利用"V"型槽方案解决泥石流沟道堆积和流通区内受地形影响水体不易下渗及疏流动力不足的问题。Aiming at the shortcomings of low survey efficiency,overlooking the entity and highlighting the locality in ground investigation of debris flow basins,this paper introduces the unmanned aerial vehicle oblique photograph technique,in order to make up for the defects of traditional survey methods and means. Constructing the engineering 3 D model with 3 D data through 3 D production software,and then put this model into the debris flow channel of aerial survey. This model can truly reflect the actual situation of the debris flow deployment and design project,and better meet the quality of the governance project effect map,and then further check the subtle flaws of the design scheme and conduct the modification on the plan. The application of "V"groove has solved the problem that the cross-section of the trench debris flow accumulation area and the circulation area reflects as V-shaped,and the terrain is flat,which causes the water body is not easy to infiltrate and the beam flow force is insufficient.
