摘要
针对龙开口水电站坝后背管的工程设计问题,采用三维有限元技术,考虑施工、运营、校核工况和以垫层钢管代替厂坝之间伸缩节等的影响,建立坝后背管的整体力学分析模型,对坝后背管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坝后背管结构设计要点,供龙开口水电站及同类水电站坝后背管结构设计参考.
Considering the influence of construction, operations, checking operating conditions and substituting the expansion joint with cushion layer,etc,3-dimentional finite element technique is adopted setting up the integral mechanical analysis model of penstock on downstream surface of dam. Main points of structural design of penstock on downstream surface of dam for Longkaikou Hydropower Station are given,which may be referenced by Longkaikou Hydropower Station and other hydropower stations in the structural design of such penstocks.
