摘要
应用三维有限元数值分析方法对坝基、坝体、闸墩、混凝土锚块及预应力锚索在内的整体模型进行应力和变形计算。研究结果表明,预应力闸墩具有整体稳定性,在各种荷载的组合效应下整个墩体的变形和应力分布满足设计要求。
Wanmipo hydropower station is used as power generati on utility. In this paper, 3-D FEA numerical method was applied to compute the stress and deformation of the whole model which consist of rock foundation,dam,s luice pier,concrete anchor-volume and the pressure vessel before prestressed an chor was stretched in order to investigate the stress and displacement distribut ion under the different load combination. So the results can be used to check th e design of the engineering and to guide the construction.
