拱坝运行期坝肩变形对岸坡溢洪道受力影响的有限元法分析

Finite element method analysis for influence of arch dam abutment to bank spillway stressing in operating period

通过有限元计算,分析龙泉市岩樟溪一级电站拦河坝在最不利工况时对岸坡溢洪道结构的应力和稳定的影响。根据计算成果,认为在采取溢洪道底板和侧墙加插锚筋后,正常的坝肩变形不会对溢洪道结构的应力和稳定造成危害。

Throngh finite element method calculation, we analyse the stress and stability of the bank spillway concrete structure in bad conditions for the dam of Yanzhangxi （ 1 ） Water Power Station in Longquan. Based on the computation result, we think that a normal abutment deformation will not create danger to the stress and stability of the spimway concrete structure after adding the spillway base plate and anchor bar in the flank wall.
