巴基斯坦杜伯华水电站工程厂房设计

Powerhouse Design of Duber Khwar Hydropower Project in Pakistan

巴基斯坦杜伯华水电站工程是一项高水头、长隧洞、引水式水电站工程。未考虑水击压力情况下总水头约538 m,共安装2台冲击式机组,单机容量达到65 MW,总装机容量130 MW。厂房位于高地震区,设计中采用整体钢筋混凝土结构。主要对厂房布置以及结构方面设计特点进行论述,希望能对高地震区建高水头、大容量冲击式机组电站设计提供一些借鉴。

Duber Khwar Hydropower Project is a diversion type power station characterized by high water head and long tunnel.The total water head is about 538m without considering water hammer pressure.Two impulse turbines are installed with unit capacity of 65MW,130MW in total.The powerhouse is situated in high seismic region,and integral reinforced concrete structure is adopted in the design.Here the feature of powerhouse layout and structural design is discussed,hoping to provide some reference for building power stations of high water head and large volume impulse turbine in high seismic region.
