本文应用三维等参数有限元法计算研究了一座坝高43米,大孔口双曲薄拱坝其坝基刚度分为坝底和左右岸坝肩三个区域的基岩弹模相互变化对拱坝变位和应力的影响,得出了对实际工程有一定参考价值的结论。
In this paper, a three-dimensional isoparametric finite element method is used to study the deformation of a dam with a height of 43 meters. The large aperture hyperbolic thin arch dam is divided into three sections: the basement stiffness and the left and right dam abutment, Displacement and stress effects, come to the actual project has some reference value conclusion.
