Abstract
To solve the shortage of land resources and the lacking of soil in expressway construction, the application feasibility of river sand and weathered mudstone rock (WMR) used for filling embankment with steep slope (slope ratio is 1:1) were evaluated in this paper. 24 kinds of embankment schemes in terms of the combinations of the river sand and WMR with different embankment heights were designed. The slope stability analyses of these embankments were conducted using numerical calculation method. The results show that the safety factors of river sand embankments with 3–4 m slope protection width (SPW) and composite embankment with 3 m SPW can meet the requirements, provided the embankment height is less than 8 m. While considering comprehensively the vertical deformation, location of potential sliding surface, and economic cost, the river sand embankment with 3 m SPW is the optimal scheme. When the embankment height exceeds 8 m, the increase of SPW has no obvious positive effect on the increase of safety factor.
