摘要
根据原型和模型观测,经过概化,本文确立了阻水河区水流模式,通过流束分解,运用流体力学基本原理,建立了壅水质量力—动量变差方程,提出了壅水特征值解法。经过实践验证,可有效应用于防洪治河,河道工程规划设计、河道管理和清障等方面的水文水力计算。
According to the prototype observation and to simplify, the paper establish a water flow mode for the river choking flow area, gives a momentum variation equation of the backwater mass force and the way to solve backwater characteristic value. It can effectively use to hydrologic and hydraulic calculation of the flood control and river control, the planning programming of the river project, the river management and the clearing barrier.
