路基施工过程变形研究的FLAC3D数值模拟OA
FLAC3D numerical simulation study on deformation of subgrade construction process
对路基在施工过程中的变形特性进行数值模拟分析,研究在不同填土重度和不同填土回弹模量的条件下,路基中心处竖向沉降和路基坡脚处的水平侧向位移随路基填土高度的变化情况,在满足规范要求的条件下,尽可能的选用重度小的填土或提高路堤回弹模量,能够改善公路沉降变形.
Numerical simulation analysis of the deformation characteristics in the construction process of subgrade is conducted. In different unit weight and modulus of resilience conditions of filled soil, vertical settlement and the horizontal lateral displacement in the embankment slope feet of roadbed center change with the change of the depth of fill. The deformation law are found, which guide practical engineering of the sub grade construction. The filled soil o…查看全部>>
