摘要
东山水闸于2013年汛期前期泄洪造成部分闸孔下游消能工遭受破坏,在出险闸孔下游消能工初步修复之后,水闸面临汛期度汛的问题。在水闸下游消能工出险原因初步分析的基础上,通过对枢纽电站运行的闸下游水位的分析和水闸下游消力池运行水力条件的计算,提出了水闸各类闸孔和闸门开度合理调度运行的度汛方案,得到了水闸调度运行的采用。研究成果可供类似工程运行参考。
The downstream energy dissipation of some gate holes of Dongshan sluice was damaged in 2013 due to pre-flood discharge in the flood season.After preliminary reparation of the downstream energy dissipation,it faced the problem of how to go through the flood season.On the basis of initial analysis of the causes of damage,and after analysis on the downstream water level during operation of the power station and calculation of the hydraulic conditions of the stilling basin,flood prevention scheme on reasonable dispatching and operation of all kinds of gate holes and gate openings is put forward,and used on the application of gate dispatching and operation.The research results can be used as reference for similar projects.
