摘要
水库大坝为我国低空防护重点目标,研究大坝隐患排查及安全管理技术,确保大坝自身的结构稳定性具有十分重要的战略意义。提出以低空无人机航飞结合倾斜摄影技术对大坝表面渗漏情况进行检测的技术方法,通过无人机数据采集、倾斜摄影建模及人工解译等手段排查大坝出现的裂缝、表面破损、渗漏等情况。以丹江口大坝为例,对其中一条溢洪道进行实地验证,准确发现多处裂缝、表面破损、渗漏等位置。实验结果表明本文提出的方法结果准确有效,较传统方法效率更高。
Reservoir dams are the key targets for China′s low-altitude protection.It is of great strategic importance to study the hazards and safety management techniques of the dam itself.This paper proposes a low-altitude unmanned aerial vehicle（UAV）combined with oblique photography technology to detect the surface leakage of the dam.It uses drone data acquisition,tilt photography modeling,and manual interpretation to check for cracks in the dam.Surface damage,leakage,etc.This paper takes the Danjiangkou Dam as an example,and conducts field verification on one of the spillways,accurately discovering multiple cracks,surface damage,and leakage.The experimental results show that the method proposed in this paper can detect the dam in real time,and the result is accurate and effective.It is more efficient than the traditional method.
