| 摘 要： | 基于水下地形实时监测技术,对河工模型水下地形冲刷发展过程进行了分析,在研究水下地形冲刷过程中,采用MATLAB为平台,对采集的数据进行了过滤处理,通过基于原始递归函数理论的曲线(面)拟合法对选取点进行插值得出水下地形冲刷过程随时间的变化曲线,用插值曲线对水下地形发展过程进行模拟,再与实测数据进行分析比较,结果证明该模拟方法可行,并对水下地形的冲刷过程研究具有一定参考价值。

| Abstract: | Based on the real-time monitoring technology of underwater topography,the paper analyzes the mechanism of scouring development process of underwater topography of a river model.During the study of scouring of underwater topography,the paper filtrates the collected data by means of MATLAB.First,based on the curve fitting method of primitive recursive function theory,the paper carries out interpolation analysis of selected points and gets a series of time-changing curves about scouring process of underwater t... |
