摘要
地形是区域环境的重要组成部分,三维地形分析为地表演化过程研究提供了全新的技术支撑。本文依托黑沙洲航道整治二期工程多期水下地形测量数据,基于BIM技术实现各个时期航道水下地形表面的三维可视化,并对其进行动态监测分析。研究表明,基于BIM技术实现航道水下地形空间监测,能够更加形象直观地展示区域地形演变、泥沙淤积等三维情况,对于航道的维护和整治具有重大意义。
Terrain is an important part of the regional environment,and 3D terrain analysis provides a new technical support for the study of the surface evolution process.Based on the multi-stage underwater topographic survey data of phase II project of Heisha River channel regulation,and adopting BIM technology,we realize the 3D visualization of underwater terrain surface of each stage,and carry out dynamic monitoring and analysis of it.The research shows that based on the BIM technology,we can realize the spatial monitoring of the underwater topography of the waterway,which can show the 3D situation of the regional terrain evolution and sediment deposition visually,which is of great significance for the maintenance and renovation of the waterway.
