摘要
本文应用灰色系统理论中的积分GM(1,1)模型对混凝土疲劳强度进行了预测,预测值与试验值吻合的很好。说明对于象混凝土疲劳强度一样具有波动性的离散数据列,积分GM(1,1)模型具有更好的预测效果,值得在混凝土疲劳强度预测中进行推广。
The fatigue strengths of concrete were predicted hy integral GM(1,1) forecting model in this paper, and the prediction results were indentical with experiments. It was evident that the discrete data sequences, such as fatigue strength of concrete full of wave preperty, would be predicted accurately by integral GM(1, l)model. And it is worthy to popularize this Grey System Theory.
