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.

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。
