摘要
通过对大坳拦河闸闸后消力池连接段稳定分析,建立了预警曲线。分析计算表明,常规上不考虑水跃因素是偏于危险的,考虑水跃是非常必要的。并在实际工程安全管理中得到应用,可为类似工程安全管理提供参考。
Based on the stabilityanalysis of the ramp connecting section of the energy dissipator,aearly warning curve is established for Daao gate dam.The analysis and calculation show that the stabilityanalysis leans to danger when hydraulic jump is not considered.So it is necessary to consider the hydraulic jump.The research findings was used in the engineering safety management which can provide a reference for the similar projects.
