【摘要】 本文从系统的观点出发，首先分析了水泵直接加压式喷灌压力管网系统的组成，继而运用图示模拟技术，着重研究探讨了计算各类水力单元直至全系统水力特性的模拟模型，并针对一个规模较大，地形较为复杂的坡地喷灌工程，具体介绍了运用该模型进行图示模拟计算的方法和步骤。计算结果表明，该模型能如实地反映喷灌压力管网系统的运行客观规律，从而为了解把握喷灌压力管网系统的水力特性提供了一种行之有效的实用计算方法。更多还原

【Abstract】 The component of pipe-net system for sprinkler irrigation with pressure from pumps diredly was analysed atfirst, then the simulation model of for calculations hydraulic charactertes for different hydraulic units and full system wasprobed emphatically in this paper. And the calculation method and stepe of using this model for a large sprinklerirrigation engineering on slope land with complicated topography were introduced. The result indicates that this model of can reflect the operation law of pressured pipe-net system for sprinkler irrigation objectively . Thercby an effcctive andPractical calculation method for understanding the hydraulic characteristics of pressured pipe-net system for sprinklerirrigation was put forward.更多还原
