摘　　要：混凝土的无侧限长期抗压强度与许多因素有关,而这些因素又是不能确定的。利用灰色系统来预测混凝土在化学损伤长期作用下的抗压强度。用加速腐蚀试验方法对混凝土抗压强度进行验证,分析比较,预测结果与实测数据较好吻合,预测结果比较精确。Concrete＇ s unconfined long-term compressive strength is related to a number of factors, and these factors are uncertain. Gray system is used to predict the compressive strength of concrete under the long-term chemical damage and to optimize the system. With the accelerated corrosion test method, we verify the compressive strength of concrete, have analysis and comparison, the predicted and measured data agree well with each other, and the result was satisfactory.
