摘　　要：文中结合丰满水电站工程设计中遇到的实际问题,以泄洪兼导流洞预应力闸墩为研究对象,利用大型有限元软件ANSYS,建立泄洪兼导流洞预应力闸墩三维有限元计算模型。计算分析了预应力闸墩在各种工况下的应力分布规律,提出结构受力的关键部位与受力特性。Combining with the existing practical problems in the design of Fengman hydropower station and taking the prestresse pier of spillway tunnel and division tunnel as the research object, the three-dimensional finite element calculation model of the prestresse pier of spillway tunnel and division tunnel are built by using the large finite element software ANSYS. The paper calculates and analyzes the stress distribution laws of the prestresse pier under various conditions and puts forward the key part of the structure stress and the mechanical characteristics.
