Study on Influence of Numerical Simulation Accuracy on High Core Wall Rockfill Dam Deformation and Crack Analysis

With the increasing height of rockfill dams, detailed and effective numerical simulation for dam design construction has become increasingly important. This paper develops a finite element program impoundment process high large-scale earth dams studies influence accuracy on deformation crack analysis. By establishing subdivision mode conventional elements, mesh generation is realized. Using row compression storage method MPI parallel method, calculation total stiffness matrix developed Linux operating system. On basis above, filling Pubugou core wall simulated, it found that zone greater than zone. Compared with process, more necessary. When simulating there significant effect result upstream side filtration So, necessary to simulate in detail. Moreover, using can accurately predict cracks.
