| Abstract: | According to the characteristics of highway engineering in the loess areas,finite element method was utilized to build analysis models under the condition of uniting the base and subgrade.Furthermore,the influence on final subsidence and non-uniform subsidence of pavement was analyzed,which was caused by many factors,such as the deformation modulus of foundation soil,the depth of earth fill,the bulk specific gravity of earth fill,the snapping back module of earth fill and other parameters,in order to guide the design of highway roadbed in loess area. |

| Keywords: | loess finite element method subsidence non-uniform rate of setting |
