改进灰色模型在基础沉降预测中的应用研究

灰色系统理论成功地解决了许多信息不完全的预测问题,并得到了广泛的应用。灰色模型的建立,是以等时距原始数据作为前提条件的。由于在实际应用时所获取的数据往往不是等时距的,难以建立其预测模型。为了克服灰色模型以上缺点,对灰色模型进行了改进,建立了不等时矩的灰色预测模型,并应用于某电厂烟囱基础沉降预测中。结果表明:改进灰色预测模型精度好。

Study on the Application of the Improved Gray Model in Prediction of foundation Settlement

A number of prediction problem of inadequacy information is successfully solved by using Grey System Theory, which is applied to everywhere. The foundation of Grey Model is based on the equal interval original data. It is difficult to establish prediction model as a result of the unequal interval data, which is obtained from the practical application. For sake of the Grey Model shortcoming, the Grey Model is improved, The unequal interval Grey Model has been built and applied from the prediction of the foundation settlement of a Power station chimney, and its accuracy has been proved.
