| 摘 要： | 结合高速公路路基施工沉降观测数据,讨论了灰色系统理论和双曲线模型在公路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,建立了任意时间间隔的非等时序改进灰色模型。通过具体工程实践,给出了灰色模型和双曲线模型对公路路基沉降量预测结果与实测结果的比较,结果表明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。

Subgrade Settlement Forecast Basing on Grey Model for Non-Isometric Time Sequence |

| Abstract: | Combined with subgrade construction settlement observation data of expressway,the application of grey system theory and hyperbolic model in subgrade settlement forecast is discussed,and grey model for isometric interval GM(1,1) is improved,thus establishing grey model for non-isometric time sequence of arbitrary time interval.Through specific engineering practice,the comparison of forecast result and actual result of grey model and hyperbolic model to subgrade settlement is given.The result shows that the f... |
