| 摘 要： | 针对土石坝的反馈分析问题,采用Fortran语言编程,实现了粒子群优化算法与商业有限元软件ADINA之间的无缝连接,使整个计算过程自动化;应用OpenMP方式同时调用多个ADINA求解器,启用多核处理器进行并行计算,提高了计算效率。以糯扎渡超高心墙堆石坝为例,对粗堆石料Ⅰ区材料应用不同种群规模粒子群进行参数反分析,结果表明,将粒子群算法与ADINA联合应用于土石坝参数反演是可行的,并行算法也具有明显的优越性。 |

| Abstract: | Focusing on the problem of the feedback analysis for earth-rock dams,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 developed 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 rockfill 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. |
