摘　　要：采用FLUENT软件数值模拟与物理模型试验相结合的方法,对某导流放空洞改建工程是否可利用其原有消能防冲设施进行了模拟计算及验证。在现状设计方案的基础上提出了两种将导流放空洞出口延长而不改变消力池布置的优化方案,并对其进行了数值模拟与物理模型试验,表明优化方案二更好,无需对下游消能设施进行较大改建即可满足消能防冲要求,能降低工程量及造价,故作为实施推荐方案。A diversion and emptying tunnel reconstruction project is studied with numerical simulations in FLUENT software and physical model tests to determine whether the original energy dissipation and scouring protection facilities can be still applicable.On the basis of the original design,two optimization schemes are proposed to extend the diversion and emptying tunnel without changing the layout of the stilling basin.The results of numerical simulations and physical model tests show that the second scheme is preferable and recommended,which can fulfill the requirements of the energy dissipation and scouring protection without large reconstruction work of the downstream energy dissipation facilities and thus reduce the engineering quantity and construction cost.
