| 摘 要： | 冲淤计算是河流、海岸、港区等水域分析和预测河床变化的基础.通过收集不同时期水下地形数据,基于Delaunay三角网生成的数字高程模型,根据河床局部空间区域体积变化,以三维空间垂直三棱柱体作为基本单元,利用VBA强大的可视化用户界面及其编程语言开发出基于AutoCAD环境下的冲淤量自动处理程序.为VBA的二次开发应用和研究提供了有益的参考.

| Abstract: | Calculation of alluvial riverbed deposition is the basis for the analysis of the water body of rivers,close to seashores and in ports and forecasting of the change of riverbeds.By collecting data of underwater terrains in different periods,based on the digital altitude model generated by the Delaunay triangulation network and the volumetric change of the local spatial area of a river,by taking the 3D spatial vertical triangular prism as the fundamental element,and by making full use of the VBA's power-ful v... |
