| Abstract: | 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. |
