| 摘 要： | 针对白水江三级水电站泄洪闸工作弧门承受水推力较大、闸墩布筋困难,采用预应力闸墩技术设计,提出了优化闸墩预应力锚索布置、张拉力锚固体系选择,并应用三维有限元法对三种工况下预应力分布进行计算分析.结果表明,该法合理可行,成功解决了弧门工作时产生的巨大推力,并可指导预应力闸墩设计.

| Abstract: | According to the difficulty of arranging reinforced bars in piers in Third Cascade of Baishuijiang Hydroelectric Station caused by the high water push to the arc gate of sluice,pre-stressing pier method is used,and the optimized pre-stressed anchor arrangement and the tensile anchoring system is applied.The pre-stress distribution under three different load combinations by 3-dimensional finite element method is analyzed,That the method employed in this paper is feasible and effective to settle the high wate... |
