Method of Using Micro-UAVRS in Engineering Geological Investigation and Design for Emergency Control of Landslides

小型无人机遥感发展迅猛并开始广泛应用于大范围地质灾害调查,但针对单体滑坡的较少。将小型无人机遥感技术引入到滑坡应急治理工程勘查设计实践中,阐述了小型无人机遥感的作用,介绍了勘查设计工作实施流程的变化以及关键技术方法,并给出应用实例。结果表明,在滑坡应急治理工程勘查设计中引入小型无人机遥感技术,既能大大减轻现场工作时间、强度和风险,也可显著提升工作效率和成果精度,还能丰富勘查设计过程及成果的形象直观表达,可以实现滑坡勘查设计目标。

Speed and accuracy were requirements of engineering geological investigation and design for emergency control of landslides,but it was difficult to achieve because the detail site work was usually restricted by field environmental conditions of landslides.The micro unmanned aerial vehicle remote sensing（micro-UAVRS）system was developing rapidly and widely used to investigate wide range geo-hazards.Based on the practice of using micro-UAVRS in engineering geological investigation and design for emergency control of landslides,the role and advantages of micro-UAVRS was introduced.Then,the new workflow and key technologies methods were elaborated.Finally,an example was presented.Practice effect indicates that using micro-UAVRS in engineering geological investigation and design for emergency control of landslides could greatly reduce the work time,strength and risks,and was able to significantly increase the efficiency and accuracy of results,and also could improve visual expression of process and results.In a word,the method was effective and capable of achieving the goal of fast accurate investigation and design for emergency control of landslides.
