基于ANFIS模型的充填体抗压强度预测研究

以新城金矿充填尾砂为试验料浆,采用正交设计法设计试验方案,研究灰砂比、质量浓度、养护龄期对充填体抗压强度的影响规律。运用极差和方差分析结果,并采用ANFIS建立预测充填体抗压强度的模型。结果表明,灰砂比是影响充填体抗压强度的最重要的因素;ANFIS模型具有95.8%的预测精度,它是预测充填体抗压强度的一种有效方法。

Study on predicting the compressive strength of filling body based on ANFIS model

Taking the filling tailings of Xincheng gold mine as the experimental slurry, the orthogonal design method was adopted to design the experimental scheme to study the influencing rules of cement-sand ratio, mass concentration and curing period to the compressive strength. Analysis of range and variance analysis were employed to test the results and using the adaptive neuro-fuzzy inference system to establish a prediction model of compressive strength. The results showed that the cement-sand ratio has the greast influence on compressive strength of filling body and those factors have the similar influence; the prediction accuracy of the ANFIS model is as high as 95.8 percent and the model provides an effective method for predicting the compressive strength of filling body.
