拱坝的安全和稳定在很大程度上依赖于坝肩岩体的应力变形程度。基于有限元分析软件ADINA,结合某工程拱坝建立三维有限元模型,模拟计算了正常蓄水位工况下的3个典型高程所在截面的应力变形情况。研究结果表明,坝肩岩体的位移、应力分布规律较好,应力变形值都在允许的范围内。

The safety and stability of arch dam is largely dependent on the stress and deformation degree of dam abutment rock mass. By using finite element analysis software ADINA, the three-dimensional finite element model for a arch dam is established to simulate the stresses and deformations of three typical cross-section under the operation conditions of normal water level. The results show that the displacement of abutment rock mass and stress distribution regularity is normal, and the stress and deformation values are within allowable range.
