基于模拟退火算法的堆石体本构模型参数反演分析

FRD at home and abroad and the analysis of the status quo, the constitutive model parameters on the numerical analysis of the accuracy of the reliability of the importance of the inversion parameter analysis has important practical significance. In this paper, a combination of domestic CFRD deformation of the measured data, using simulated annealing algorithm, first for primary and secondary Rockfill Duncan Chang E－B model parameters sensitivity analysis, in accordance with the level of sensitivity of each parameter to determine the required parameters inversion for φ, K, Rf and Kb. According to the material set up at district and construction of three-dimensional finite element model, collate observations, by observing the data for parameter inversion of the margin analysis. According to the settlement collate the results of inversion parameters. The results show that simulated annealing algorithm using intelligent optimization methods such parameter inversion, can be carried out multiple parameters of inversion speed, high precision inversion.
