在进行低水头引水枢纽设计时 ,必然会遇到决定如引水枢纽畅泄冲沙水位、各闸的单宽流量或闸室净宽、各闸底板高程、各闸之间的相对高差等参数问题。本文通过分析闸前水流及过闸水流的水力学关系 ,提出了设计参数选取的一般原则及关联关系式。应用这些设计参数选取原则及关联关系式 ,可以帮助工程设计人员比较迅速的完成低水头引水枢纽的整体布置设计及水力学计算 In the design of low water head diversion project, it is bound to encounter such as the diversion project flushing flushing water level, the gate of the single-wide flow or gate width of the net, the brake floor elevation, the relative height difference between the gate and other parameters problem. In this paper, by analyzing the hydraulic relationship between gate flow and gate flow, the general principles of selecting design parameters and their relations are proposed. The application of these design parameters to select the principles and relationships, can help project designers to complete the relatively low water headwater hub layout and hydraulic design of the overall calculation
