摘　　要：由于蒲石河抽水蓄能电站闸前水位较高,水推力大,传统的钢筋混凝土结构不能满足强度和刚度方面的要求。针对这个特点,建立预应力空腔式锚块闸墩模型来模拟闸墩在几种工况下的应力,并对结果进行了详细分析。结果显示计算模型可以真实地反映物理模型的应力应变状态。计算结果为蒲石河抽水蓄能电站预应力闸墩设计及施工提供了重要的依据。Because of the high water level and the big water pressure of the Pushi River Pumped Storage Power Station, traditional ferroconcrete structure couldn＇ t statisfy the need of intensity and rigidity. The article establishes a prestressed hollow anchor block pier model simulating the stress of the pier with several working conditions and analyses the result in detail; the calculating model really reflects the state of stress and strain about physical model, so the computed result can provide important basis of the design and construction of prestressed pier of the Pushi River Pumped Storage Power Station.
