摘要
本文通过利用灰色系统理论对混凝土结构剩余寿命进行预测研究,论述了灰色GM(1,1)模型的建立,计算及原点精度检验方法,并结合实例给出了一种模型优化的途径,即参数优化法,通过与实例进行比较,证明这种预测方法是简便易行的,可靠的,准确的。
This paper presented the method for predicatiing the remaining life of concrete structures by the optimization method of Gray System Theory. The GM(1, 1)establishing, model calculation and method of origin precision analysis have been described. A method of model optimization was given. The prediction results were compared with the example. It was shown that this predicting method by Gray System was easy to implement, reliable and exact.
