摘　　要：通过利用大型通用有限元程序ANSYS，结合设计中采用的预应力锚索布置及数量等实际情况，拟对居甫渡水电站新型预应力闸墩进行三维有限元计算分析，考虑了可能发生的多种荷载工况组合，研究了闸墩的受力特征和规律，指出其预应力效果是明显的，可以大大改善闸墩结构的受力状态。并为实际工程设计提供依据，也为结构设计复核提供了重要的参考依据。Through the 3D-FEM analysis of the Jupudu hydropower station pre-stressed pier by ANSYS soft, combining with pre-stressed anchor arrangement, quantity and other reality conditions. It also considered possible diversified combination of loading and indicated that the effect of its pre-stressed action is fruitful compared with its conventional counterpart by study of mechanic calculation in comparison. As a result, it vastly improved burdening state of pier. So the results can be used to check the design of the engineering and to guide the construction.
