粒子群算法和ADINA在土石坝参数反演中的联合应用
A combined application of particle swarm optimization algorithm and ADINA for parametric inversion of earth-rock dams
摘要
Abstract
rot-using on the problem of the feedback analysis for earth-mclk Hams, the present study realizes a seamless connection between the particle swarm optimization algorithm and the large commercial finite element software ADINA with the FORTRAN programming, and devrluped an automated calculation process. The computation efficiency is improved by applying the OpenMP mode for calling the ADINA and invoking multiprocessor computers to achieve parallel computing. By taking the super high core rock-fill dam of the Nuozhadu hydropower station as an example, the parametric inversion was conducted for the data analysis of coarse rotkfill materials of Zone. 1 with different population sizes. The results indicate that the combined application of particle swarm optimization algorithm and ADINA for the parametric inversion of earth-rock dams is feasible, and the parallel algorithm has obvious advantages.关键词
