【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。
[Abstract]:Crescent ribbed steel bifurcation pipe is one of the most widely used bifurcation pipes in many hydropower stations at home and abroad because it has the advantages of simple fabrication and installation, small structure size and good water flow state. At present, a large number of research work has been carried out on the crescent rib steel bifurcation pipe, and a lot of engineering experience has been accumulated, but there are still some problems that have not been fully known and recognized by the researchers or designers. In this paper, the shape design of bifurcation pipe, stress control standard, combined bearing mechanism of buried steel bifurcation pipe, This paper introduces the latest research progress of crescent rib steel bifurcation pipe in hydropower station from the development of computer aided design system and the directional performance of ribbed plate thickness, and gives some suggestions on the selection of relevant design parameters in combination with extensive engineering examples. Based on the summary and analysis of related research results, a more definite design direction is put forward, which can be used as a reference for the design of crescent rib steel bifurcation pipe and related scientific research work of hydropower station.
