摘要
文章采用三维非线性有限元法,对那比重力坝6号溢流坝段进行破坏模式及稳定性的研究,确定其在超载法下的破坏模式及稳定安全系数,并利用多重网格法对可能的滑移路径进行危险滑块搜索,从而确定出最不利的滑出路径。
Based on 3D nonlinear finite element method,the failure pattern and stability of 6# overflow section of Nabi RCC gravity dam is studied,and the failure pattern and the stability safety factor of the same are figured out through overload method.Moreover,multigrid method is used to search for dangerous slide block along potential slide paths in order to determine the most unfavorable slide path.
