| 摘 要： | 运用灰色理论建立了土石混填路基的非等时距预测模型,同时,为了预测土石混填路基工后沉降,建立了土石混填路基工后沉降的GM(2,1)模型。通过实例计算表明,GM(2,1)模型预测精度较GM(1,1)灰色模型高,在土石混填路基工后沉降预测中具有较大的实用价值。

| Abstract: | An anisochronous and anisochronous model of mixed rock/soil filled subgrade is set up by using the grey system theory. At the same time,a GM (2,1) model is also established to forecast the settlement in the mixed rock/soil filled subgrade. The actual example calculation shows that the GM (2,1) model has higher forecast precision than GM (1,1),and thus has greater application value in the resettlement forecast of mixed rock/soil filled subgrade. |
