摘要
以松原市无名泄支河为例,使用HEC—RAS软件计算河道水面线。采用恒定流计算常水位工况下无名泄支河的水面线。采用非恒定流计算20年一遇洪水工况下的水面线。根据计算结果验证河道断面及箱涵规模的合理性。
Wu mingxie River is set as an example for water surface profile calculation by HEC-RAS. This article uses steady flow analysis to compute water surface profile in normal water level and use unsteady flow analysis to computer water surface profile in flood level which occurs once in twenty years. Rationalization of designed river cross section and culvert is discussed according to the computed results.
