Numerical Simulation of High Filled Embankment on Slope Soft Foundation

This paper building a high filled embankment FLAC^3D model by GOCAD, which embankment is on slope soft-soil foundation of Chen-Ning highway in Hunan Province. The FLAC^3D program was been adopted to simulating and analyses the embankment's deformation and stability under its own weight when layered filling. The following conclusions:The displacement of embankment is significantly affected by the landscapes;With the increase of embankment height,the settlement of embankment increases,and the position of largest settlement is about at one-third of filling height in the interior of this embankment;With the increase of embankment height,the lateral displacement of embankment presented to deformation on both side.
