摘　　要：龙滩水电站溢流坝表孔承担全部泄洪任务,其工作弧门承受水推力较大,设计采用预应力闸墩技术。本文简要介绍预应力闸墩初步设计全过程,并应用三维有限元法对其应力分布规律进行了详细研究。The spillway surface outlets of Longtan Hydropower Station take the task of flood discharge, and prestressed pier technology is used, considering the high water thrust born by its service radial gates. A brief introduction is made to the whole preliminary design process of the prestressed pier, and a detailed study is carried out for analyzing its stress distribution law by way of 3D FEM.
