三维地面模型测量技术在水运工程中的应用

码头、航道等水运工程的三维设计、BIM设计需要更精细的、直观的、全覆盖的三维地面模型。利用多波束测深技术、无人机航测技术和三维激光扫描技术采集高精度的测量点云数据,基于AutoCAD、Civil 3D等软件平台,建立高精度、直观的三维地面模型的技术方案,结合工程实例进行论证分析。结果表明,从陆域到水域再到局部重点建构筑物三维测量内外业技术解决方案合理、效果显著,能较好地满足三维设计、BIM设计等要求,具有较高的应用和参考价值。

Application of three-dimensional ground model survey technology in port and waterway engineering

The 3D design and BIM design of wharf and waterway engineering need more precise,visual and fully covered three-dimensional ground model.We collect high precision measurement point cloud data by using multi-beam bathymetric technology,UAV aerial survey technology and 3D laser scanning technology.Based on the software of AutoCAD and Civil 3D,we establish a high-precision and intuitive 3D terrain model for demonstrating,and analyze it with engineering examples.The results show that the solution of three-dimensional measurement and internal and external technical solution from land to water of local key construction is reasonable and effective.It can meet the requirements of 3D design and BIM design,and it has high application value and reference value.
