摘要
基于有限元分析软件ABAQUS,结合梅峰双曲拱坝建立三维有限元拱坝模型,研究了拱坝的失稳模式、渐进破坏发展过程及坝肩稳定安全系数,验证了由刚体极限平衡法得到的安全系数与强度折减法得到的折减系数在物理意义上具有一致性,且在允许误差内,数值具有近似性。
Based on the finite element analysis ABAQUS software,three dimensional finite element arch dam model is established with combination of Meifeng double curvature arch dam.It studies the instability mode,progressive damage development process and abutment stability safety coefficient of arch dam.The safety factor with rigid limit equilibrium method is consistent in reduction coefficient with strength reduction algorithm in the physical significance.Furthermore,the numerical value is approximate and the permissible error is acceptable.
