摘要
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 。
To design a low-head control division project, the question deciding parameters will be met, such as: free flushing water levels, discharge per unit width of gates, net width of gates, elevation of gate sill, relative differences of heights of gates. By analysis of hydraulic relations of flow before gates and through gates the article suggests the principle and formula on selecting parameters which helps designers to finish design on the general layout of division project and hydraulic calculation.
