摘要
基于地质目标计算机辅助设计软件COCAD,建立了郴宁高速公路某软土地基斜坡高填路堤的FLAC^(3D)模型,并应用FLAC^(3D)软件对该路堤的分层填筑作数值模拟,分析了路堤在填筑体重力作用下的变形规律及其稳定性。得出如下结论:地形地貌对路堤位移影响较大;随着路堤填筑高度的增加,路堤沉降逐渐增大,最大沉降约位于填筑体内部填筑高度三分之一的位置;随着路堤填筑高度的增加,路堤侧向位移大致呈现向两侧变形的趋势。
This paper building a high filled embankment FLAC3Dmodelby GOCAD, which embankment is on slope softsoil 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 emban ment; With the increase of embankment height, the lateral displacement of embankment presented to deformation on both side.
