考虑旁侧入流水面曲线一维水力学模型及应用

One-dimensional hydraulic model for calculating water surface curve considering side inflow and its application

为得到某防洪工程的水面曲线,依托新疆某地区拟建堤防工程,综合运用水文学、数学、水力学知识,借助于计算机建立了考虑旁侧入流计算水面曲线一维水力学模型,结果显示:50年一遇水面曲线计算推求结果低于设计堤顶高程约2~3m。考虑旁侧入流一维水力学模型水面曲线计算结果是更加合理的,可为同类其他堤防工程设计和安全运行提供借鉴。

In order to obtain the water surface curve of a flood control project,relying on the proposed dike project in a certain area of Xinjiang,using hydrology,mathematics and hydraulics knowledge,an one-dimensional hydraulic model for calculating the water surface curve considering the side inflow is established by means of computer.It is shown that the calculation result of the 50year water surface curve is lower than the design elevation of about 2~3m.It is more reasonable to consider the calculation result of the water surface curve of the one-dimensional hydraulic model of the side inflow,which can provide reference for the design and safe operation of other similar embankment engineering.
