The high embankment is divided into two types of zones according to the settlement amount, the pavement settlement affected zone which mainly controls the embankment settlement and the non-pavement settlement affected zone which mainly controls the slope stability. Based on the functions and bearing capacity of the two types of zones, according to the characteristics analysis of the packing gradation and compaction curve, the relationship between the compaction degree and the elastic modulus and CBR, the classification method of the filling, the pre-zoning method of the excavation area and the filling selection method are proposed; taking the high fill embankment of granite residual soil as an example, this paper also analyzes the zoning filling methods of high fill embankment from excavation zoning, filling selection, zoning paving and filling to intelligent compaction control, which provides a new idea for controlling the construction quality of high embankment; Finally, by using finite element software to compare and analyze the non soil rock mixed filling scheme, the bottom cushion soil rock mixed filling scheme and the partition filling scheme, it is concluded that the partition scheme can achieve the effect of land saving by steepening the slope with its high stability coefficient advantage over other filling schemes.
