摘　　要：月牙肋钢岔管具有制作安装简单、结构尺寸小、水流流态好等优点,是国内外众多水电站中应用最为广泛的岔管类型之一。目前针对月牙肋钢岔管已经开展了大量的研究工作,也积累了相当丰富的工程实践经验,但是仍有一些问题未被研究或设计人员所完全熟知和认同。本文主要从岔管体型设计、应力控制标准、埋藏式钢岔管联合承载机理、计算机辅助设计系统的开发以及肋板厚度方向性能5个方面介绍了水电站月牙肋钢岔管的最新研究进展,结合广泛的工程实例给出了相关设计参数的取值建议,并基于相关研究成果的总结分析,提出了比较明确的设计导向,可为水电站月牙肋钢岔管的设计以及相关科研工作等提供参考。Crescent-rib steel bifurcation is one of the most widely applied bifurcation type in hydropower station all over the world, with the following advantages of convenient manufacture and installation, ade- quate structure size, and reasonable flow pattern. A lot of research works on crescent-rib steel bifurcation have been well documented as well as the engineering practice experience. However, full acknowledgement has not been achieved on some issues of crescent-rib steel bifurcation. In this study, the latest researches of the crescent-rib steel bifurcation are presented in five aspects, including shape optimum design, stress control criterion, combined bearing mechanism of embedded steel branch pipe, computer aided design sys- tem, and bearing capability in Z-direction of the steel rib. The values of related design parameters are pro- posed based on a wide range of engineering practice while the guideline for the research and design of the crescent-rib steel bifurcation are yielded, which can be a well reference through the related design and re- search work of the crescent-rib steel bifurcation of hydropower station.
