摘要:近年来随着我国经济水平的不断提高，国家加大了对基础设施的投资建设力度。在桥梁工程建设方面，在役桥梁使用年限不断增长，桥梁结构及相应病害问题逐渐凸显，进而对桥梁的检测与维护工作提出了更高的要求。本文在分析了现阶段我国传统桥梁检测方法的诸多不足和局限后，提出了基于BIM的无人机桥梁检测实施方案，探讨了BIM技术与无人机这一辅助手段在桥梁检测方面的充分结合以及其应用可行性，为未来桥梁检测技术水平的提升提供参考依据。

Abstract: With the recent continuous improvement of China′s economic level, the national investment on infrastructure constructionhas been increased significantly. In the bridge construction area, the service life of the bridge is constantly growing, andcorrespondingly, the problems on bridge structure disease are increasingly prominent, which claims for higher request on following facility maintenancework. This paper firstly analyses the deficiencies and limitations of present bridge-detection method, then puts forward a BIM UAVbridge detection implementation scheme, and further discusses the combination of BIM technology and UAV and its application in bridge detection. This paper will provide the reference for the future upgrade of bridge detection technology.
