| 基于无人机摄影测量技术的滑坡变形研究
摘要
我国是滑坡灾害最多的国家，滑坡灾害往往造成人员伤亡，道路掩埋，房屋损毁，严重威胁着国家和人民的生命财产安全。为减少滑坡灾害带来的严重危害，科学准确的预测预报是关键。滑坡变形是指斜坡岩土体在一些因素的影响下，沿着滑坡带发生的滑移现象。滑坡变形是一种严重的地质灾害，对工程建筑、江河水资源、生态环境以及人们的生命财产有重大的威胁。因此，研究滑坡的形成及变形破坏机理，找出预防、治理策略是十分必要的。而治理滑坡变形，目前最好的方法就是用无人机摄影测量技术。
本文以滑坡变形硏究为出发点，叙述了无人机摄影测量技术的优缺点，对无人机摄影测量技术的原理、作业流程、组成和优势进行了简单介绍。说眀了基于无人机摄影测量技术的滑坡变形观测和硏究方向的思路，并指出该技术存在的问题及目前较好的解决办法。最后对无人机摄影测量技术在滑坡变形观测方面的应用进行了总结和展望，为今后相关领域的工作提供学习和思路。

Research on Landslide Deformation Based on UAV photogrammetry technology
Abstract
China is the country with the largest number of landslides.Landslides often cause casualties, road burying and house damage,which seriously threaten the life and property safety of the country and people. In order to reduce the serious harm of landslide disaster, scientific and accurate prediction is the key. Landslide deformation refers to the sliding phenomenon of slope rockand soil along the landslide belt under the influence of some factors. Landslide deformation is a serious geological disaster,which has a great threat to engineering construction, river water resources, ecological environment and people's life and property. Therefore, it is necessary to study the formation and deformation mechanism of landslide and find out the prevention and treatment strategies. At present, the best way to control landslide deformation is to use UAV photogrammetry technology.
Taking landslide deformation research as the starting point,this paper describes the advantages and disadvantages of UAV photogrammetry technology, and briefly introduces the principle, operation process, composition and advantages of UAV photogrammetry technology. The idea of landslide deformation observation and research direction based on UAV photogrammetry technology is described, and the existing problems and better solutions are pointed out. Finally, the application of UAV photogrammetry technology in landslide deformation observation is summarized and prospected,which provides learning and ideas for the future work in related fields.
Keywords：UAV; Photogrammetry technology; Landslide deformation
