| 摘 要： | 基于目前灰色理论模型在变形监测中的应用,分析了PGM(1,1)模型中的参数及其求解的方法.引入人工鱼群算法求解背景值和初始值的修正项,通过人工鱼群算法求解得到模型的最优组合值。结合大坝变形监测工程实例进行计算分析,结果表明利用人工鱼群算法(AF)求解得到的PGM(1,1)模型的背景值参数与初始值修正项对大坝变形监测的预测具有较好的效果。

| Abstract: | Based on the GM(1,1) model in the deformation monitoring,the parameters of PGM(1,1) is analyzed and find the methods of solution.Bringing the artificial fish swarm algorithm for solving the background value and initial value of modifications,through calculating and analyzing the engineering example of the dam deformation monitoring.It shows that the obtained background value and initial value of modifications of PGM(1,1) model for using the artificial fish swarm algorithm have the batter precision to predict deformation monitoring of dam. |
