镇扬河段整治工程实施后河道地形冲淤分析

Analysis on River Course Topographic Flushing and SiltationAfter the Implementation of the Zhenyang River Regulation Project

通过采用超高分辨率的浅水多波束系统对镇扬河道整治工程的水下地形进行定期监测,获取全覆盖、高精度的水下地形数据,通过分析多波束监测数据对工程现状进行定性描述。利用GIS空间分析功能对工程现状进行多维度的定量分析。通过分析结果可以发现异常现象并对其进行空间定位,以便及早采取对策,确保工程安全,同时掌握工程河段河势变化情况,为防洪抢险、河道综合整治、险工护岸等提供科学依据。

The underwater topography of Zhenyang river regulation project is regularly monitored by using ultra-high resolution shallow water multi-beam system to obtain full coverage and high-precision underwater topography data,and the project status is qualitatively described by analyzing multi-beam monitoring data.GIS spatial analysis function is used to make multi-dimensional quantitative analysis of the project status.Through the analysis results,abnormal phenomena can be found and spatially located,so as to take countermeasures as soon as possible to ensure the safety of the project,and grasp the changes of river regime in the project reach,providing scientific basis for flood control and rescue,river comprehensive regulation and dangerous engineering revetment.
