摘要
讨论了灰色系统理论在路基沉降预测中的应用,并对等间隔的灰色模型GM(1,1)进行了改进,建立了任意间隔的非时序改进灰色模型。通过具体工程实践,给出了两种模型对路基沉降量预测结果与实测结果的比较,结果表明改进灰色模型的预测沉降量与实际沉降量更接近,精度更高,更能满足工程需要。
This paper deals with the application of the improved gray theory to the prediction of subgrade settlement and improvement of equally spaced gray model GM （1.1）. A improved arbitrary spaced and non - sequential gray model is established. The results of the prediction of subgrade settlement by the two models are given by specific engineering practice which indicate subgrade settlement value predicted by the improved gray model is closed to the reality.
