Civil 3D和HEC-RAS在河道模型建立与水面线计算中的应用

Application of Civil 3D and HEC-RAS in river modeling and calculation of water surface Profile

水面线计算是河道治理工程中的重要内容,同时水面线也是工程方案设计的重要依据。对于测量断面较多的河流,水面线模型的建立需要花费比较长的时间和精力,Civil 3D的建模功能结合HEC-RAS的水面线计算功能,可以快速地建立河道模型并进行水面线计算,相对于传统的河道模型建立和计算,两个软件的结合应用不仅速度快,而且模型更加准确和直观。

For a river harnessing project,water surface profile is the key basis of scheme design,so its calculation is important.For a river with many measuring sections,water surface profile modeling requires much time and work.Combination of the modeling function of Civil 3D with the water surface profile calculating function of HEC-RAS is able to accelerate the river modeling and calculation.Compared with traditional river modeling and calculation,the combined application of two software permits quicker work,more correct and visual model.
