摘　　要：大花水水电站泄洪中孔主要功能为参与泄洪,中孔出口设置弧形工作闸门,该闸门孔口尺寸为6 m×7 m(宽×高)、设计水头为63 m,单边弧门支铰推力较大。根据结构构件计算结果并综合有限元分析成果,中孔闸门闸墩设计采用了预应力锚索技术。本文重点介绍了大花水水电站泄洪中孔预应力闸墩的布置设计。Radial gates are installed in the middle discharging orifices of Dahuashui Hydropower Station. The size of a gate is 6m ×7m （width × length）, its design head is 63m, the thrust on the hinged bearing of the gate is bigger. According to the results of calculations including finite element method, pre-stress anchorage cables were adopted in pier design for gate of meddle orifices. The paper mainly introduces layout design of the pre-stress piers.
