摘要
应用大型结构计算软件ANSYS,对丰满重建工程溢流坝预应力闸墩进行三维有限元模拟计算与分析。通过从锚索吨位、次锚索位置、空腔措施、锚块尺寸以及锚块底部与闸墩接触方式等方面开展研究,对预应力闸墩进行优化分析,从而改善闸墩的受力状态,提高预应力效果。同时为有关预应力闸墩研究提供了参考依据。
With large structural calculation software ANSYS, the 3 - D FEM simulative calculation and analysis are made on the prestressed pier of the overflow dam for Fengman hydropower Station Reconstruction Project. Through the studies carried out in the aspects of the main anchor cable tonnage, the secondary anchor cable position, the cavity arrangement, the anchor block size, the mode of the contact between both the bottom of the anchor block and the pier, etc. , a optimized analysis is mad on the prestressed pier, and then not only the stress state of the pier is improved, but its prestressed effect is also enhanced. Mean- while, a reference basis is laid for the relevant study on prestressed pier as well.
