高性能混凝土三种强度预测方法比对

Comparison of three different strength forecast methods for high performance concrete

高性能混凝土强度的预测方法大多参考普通混凝土强度预测方法。以标准养护下的高性能混凝土强度实验数据为例,分别应用鲍罗米公式、Matlab曲线拟合和灰色预测三种方法进行分析,并比较其误差,选择最优分析方法。根据试验测试结果以及综合分析三种方法后得出其强度预测方法精度由高到低依次为:灰色预测,Matlab曲线拟合,鲍罗米公式。

Most strength forecast methods of high performance concretes arc similar to the method of ordinary concrete. The experimental datas of HPC strength under standard curing were analysed respectively by Bowromi formula, Matlab Curve Fitting and Grey Forecasting, and the errors were compared to select the best method. Finally, according to the test results, the precision sequence of the three methods are as follows：Grey Forecasting〉 Matlab Curve Fitting〉Bowromi Formula.
