摘要
本文应用灰色系统理论对混凝土疲劳强度进行研究 ,并建立了单变量的一阶灰色预测模型GM (1 ,1 ) ,对混凝土的疲劳强度进行预测。通过与试验值的比较 ,证明这种预测方法是简便易行、可靠的 ,也是一种可以大大减少试验工作量 ,缩减试验周期的疲劳强度预测方法。
This paper presented the method of researching the fatigue strength of concrete by Gray System Theory.The GM(1,1) model for predicting fatigue strength of concrete was established.The prediction results were compared with experiments by other authors.It was shown that this predicting method by Gray system was easy to implement and bereliable,and which could decrease the worklodad and cycle of fatigue experiments sharply.
