摘　　要：介绍了长潭岗水电站反拱形水垫塘的布置型式和结构构造,用有限元的方法计算了动水荷载作用下的底板应力和位移,通过水工模型试验,测试了底板上的动水压强.本工程已经建成,并埋设了结构和水力学原型观测仪器.长潭岗拱坝反拱形水垫塘的应用研究,可为大型水电站拱坝水垫塘型式选择提供借鉴.In this paper,the arrangement and structure of the counter-arch slab plunge pool in the Changtangang Hydropower Station are presented.The stresses and displacement of counter-arch slab under hydrodynamic loads are calculated by FEM.The hydraulic pressure of slab is obtained by hydraulic model experiment.For monitoring the safety of the plunge pool,both structure and hydraulic instrument for prototype observation are installed.The plunge pool of Changtangan g Hydropower Station presents an exam ple to use counter-arch plunge pool in large scale hydropower projects.
