软基地段斜坡高填路堤施工数值模拟
软基地段斜坡高填路堤施工数值模拟
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FLAC3D模型,并应用FLAC3D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。
Abstract:This paper building a high filled embankment FLAC3D model by GOCAD, which embankment is on slope soft-soil foundation of Chen-Ning highway in Hunan Province. The FLAC3D 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.
