摘要
冲淤计算是河流、海岸、港区等水域分析和预测水下地表变化的基础。通过收集不同时期水下地形高程值,基于Delaunay三角网生成的数字高程模型,以三维空间垂直三棱柱体为基本单元,计算出河、海床面局部空间区域体积变化量。利用VBA强大的可视化用户界面及其编程语言,以国家大型工程为应用实例,开发出嵌入于AutoCAD环境中的冲淤量自动计算程序。
The analysis and forecast of riverbed change is based on the riverbed deposition calculation on the water area of river, seashore, port and so on. Delaunay digital elevation Model is created by Delaunay triangulation on the different time data. The volume of some areas can be computed by units of 3-D mathematical model. Rivered Deposition Calculation Program within the AutoCAD environment is developed on the basis of making full use of VBA powerful preview UI,program language and large state project as the application case.
