【摘要】 本文通过大量系统的试验研究,得出了U形渠道直壁槽式量水堰的体型参数、水流流态及水尺位置,研究了这种量水堰的测流原理,并提出了自由出流和淹没出流时简单实用的计算方法。文中还列举了三个典型的算例可供工程设计和管理应用参考。更多还原

【Abstract】 In this paper, based on a lot of systematic experimental research to the straight wall trough measuring weir of U-shaped Channel,the type of build parameter, flow pattern and the place of water gauge were obtained. Flow measurement theory of this type of measuring weir was researched, and a simple and practical calculation method for free and submerged flow was presented. Three typical examples were enumerated in the paper, so that to give a consultation for engineering design and management.更多还原
