摘　　要：为预测海水侵蚀作用下混凝土抗冻强度与冻融循环次数的关系,根据灰色系统理论,利用GM(1,1)预测模型,依据试验数据建立了海水作用下混凝土抗冻强度预测模型.计算分析比较表明,其预测结果与实测数据吻合较好,结果比较理想.In order to forecast the relation of concrete strength with the times of freezing and thawing circulation, according to the GM（1,1） forecast model of gray system, this paper established a gray forecast model of concrete strength thai resists freezing and thawing on the basis of test data in seawater. According to calculation and analysis, good agreement is reached between the theoretical predictions and available test results. As a resuh, this gray forecast model can be used to forecast the concrete strength development.
