船闸短廊道和三角门门缝联合输水的水力计算

结合依托的船闸工程,提出了短廊道和三角门门缝联合输水的水力计算方法,并通过对输水系统的水力计算分析,确定了阀门处廊道断面尺寸,提出了具体的输水系统布置,确定了输水阀门的开启方式。建立了短廊道和三角门门缝联合输水的输水过程数学模型,并采用该数学模型计算了船闸输水水力特性。水力特性计算结果表明,进行输水系统布置时,将短廊道和三角门门缝分开考虑进行计算分析是合适的,各项水力特征值满足设计和规范要求,并且该输水方式可提高船闸运行效率。

Hydraulic calculations of the lock shod culvert associated with sector gate gap filling and emptying system

A hydraulic calculation method about the lock short culvert associated with sector gate gap filling and emptying system is put forward in a lock project.According to calculations and analyses on filling and emptying system,the crossing culvert dimension at the valve and the concrete disposal of the lock filling and emptying system are designed,at the same time,valve opening speeds are recommended.A mathematical model about short culvert associated with sector gate gap filling and emptying is established,and the hydraulic characters during lock filling and emptying are calculated by the model.The study results indicate that it is suitable considering the short culvert and the sector gate gap separately.The characters are coincident with design and criterion demands,and the filling and emptying mode can raise lock's run efficiency.
