摘要
以克塔铁路路基稳定性研究为工程背景,利用有限元数值仿真分析软件ADINA建立二维路基计算模型,通过改变不同路基面层刚度,研究了克塔铁路路基的稳定性问题。有限元数值分析结果表明:随着路基面层刚度的增加,路基沉降变形和侧向位移减小。
Taking the roadbed stability research on Keta railway,this paper established two-dimensional roadbed calculation model using finite element numerical simulation analysis software ADINA,through changing the base layer stiffness of different roadbed,researched the stability problems of Keta railway roadbed,the finite element analysis results showed that： with the increase of roadbed base layer stiffness,the roadbed settlement deformation and lateral displacement were reduced.
