摘　　要：针对水电站引水压力管道的受力和结构设计问题,以龙开口水电站引水压力管道为研究实践对象,采用三维有限元技术,考虑施工、运营,校核、取消厂坝伸缩节等因素的影响,建立引水压力管道的整体力学分析模型,对引水压力管道各段的受力特性进行了计算分析研究,给出了龙开口水电站引水压力管道结构设计要点,并就进水口渐变段结构设计及取消厂坝之间伸缩节后垫层钢管结构设计给出一些提议,供同类水电站引水压力管道结构设计参考。In this paper, considering the influence of construction, operations, checking operating conditions and canceling the expansion joint, 3-dimentional finite element technique is adopted setting up the integral mechanical analyzing model of diversion penstock, and calculating the stress of each part of the diversion penstock. Main points of structural design of diversion penstock in Longkaikou Hydropower Station and some suggestions for the structural design of power intakes transition and penstock with cushion layer replacing expansion joint are given, which may be referenced by hydropower stations in the structural design of such penstocks.
