摘要
针对山区河流河势变化复杂的特点,以北溪城区段河道防洪工程设计为例,采用HEC-RAS软件建立一维水动力学模型,模拟山区实测地形及沿河存在涉水建筑物条件下的洪水水面线。复核了原有防洪工程,并提出优化设计措施,提高了河道行洪能力,也为断面形式复杂的山区河流防洪工程设计提供依据。
Aiming at the complex characteristics of river regime change in the mountain river, and taking the design of Beixi City Area River Flood Control Project as an example, the HEC-RAS software is used to establish one-dimensional hydrodynamic model for the simulation of the measured terrain in the mountainous area and the flood flow profile under the condition of water buildings existing along the river. The original flood control projects are rechecked, the optimization design measures are proposed and the river flood discharging capacity is improved, which provide a basis for the design of flood control projects of mountain river with the complex section form.
