摘要:
 依托武穴长江大桥北岸接线段工程,根据沉降监测实测数据,采用三次样条插值方法将非等时距实测数据转换成等时距序列,建立等时距灰色GM(1,1)模型。利用matlab编程对模型进行计算,对处理后的软基沉降进行预测。利用经典的双曲线法和三点法分别进行沉降预测,并将预测曲线与基于等时距的灰色模型预测曲线进行对比,结果表明:灰色GM(1,1)模型预测精度更高,预测结果更可靠。基于等时距的灰色模型为软基处理后的沉降预测提供一种重要方法,对软基处理的施工具有一定的指导意义。
Abstract:
 In order to solve the problem of soft ground settlement on the expressway of the North Bank Connection Section of the Wuxue Yangtze River Bridge Project, according to the observed settlement data and based on the grey system theory, the non-isochronous measured data are converted into isochronous series by cubic spline interpolation method. The grey GM (1, 1)model is established and the soft foundation settlement prediction curve is calculated by Matlab programming. The curve is compared with hyperbolic method and three-point method. The results show that the prediction precision of GM (1, 1) model is higher and the prediction result is more reliable, which can provide the scientific decision-making basis for the similar engineering soft soil roadbed settlement prediction.
