摘要
本文根据丘陵区管道水力特征，采用管网非恒定流代数解法，建立了丘陵区封闭及半封闭管网压力分布特征计算的数学模型，提出了相应的简化计算方法及收敛判据，并同传统的计算方法进行了分析比较。
In this paper,a mathematical mode of pressure distribution characteristics in opentype and chose-type pipelines installed in hilly areas is established according to hydraulic characteristics of pipelines and on the basis of algebraic method of transient flow in pipelines.Moreover,a simplified calculation method and the judgement convergence method are proposed and comparisons with normal methods are made.
