砼强度的BP网络模型

The BP ANN model of concrete strength

通过分析影响砼强度的因素,建立了一个3层的BP网络模型,在对样本进行分类和标准化处理后,进行了BP网络的训练和仿真,其结果表明:应用所得到的BP网络对于砼强度的预测值计算相对于实测值具有满足工程要求的精度.

This paper establishes a BP ANN model with 3 layers through analyzing the influence of concrete strength. After the classification and standardization of the sample, the BP ANN model is trained and simulated. The results indicate that the stimative values calculated by the BP ANN model have the enough accuracy compared with the actual values, and its accuracy can satisfy the demand of the engineering.
