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.
