摘　　要：导流洞封堵闸门作为一个复杂的三维空间结构,在设计时需要考虑其空间效应,而传统平面体系法无法考虑各部件间的变形协调。以某水电工程导流洞封堵闸门为例,建立了大型封堵闸门的有限元分析模型,对各种运行工况下闸门的静应力、屈曲失稳及动力特性进行了空间计算分析,为闸门结构设计提供了详细可靠的依据,对同类闸门设计计算具有参考意义。As a complex three-dimensional space structure,spatial effect of the diversion tunnel gate needs to be considered in its design,but the traditional planar system method cannot consider the deformation coordination of each component.The article takes the diversion tunnel gate of a hydropower project as an example,establishes finite element analysis model of a large-scale gate,and spatially calculates and analyzes the static stress,buckling instability and dynamic characteristics of the gate under various operating conditions,which provides a detailed and reliable basis for the gate structure design.The analysis is of reference value for the design calculation of similar gates.
