Abstract: Using the FEM program with Duncan nonlinear elastic model, this paper analyses the behaviours of stability and settlement of embankment in mountainous land with different treatment regions and filling rates, and finally, the author analyses the settlement behaviours of three embankment in longitudinal and transverse direction.

Key words: embankment in mountainous land, FEM, treatment regions, stability and settlement

摘要： 采用非线性弹性的邓肯模型编制的有限元程序,对山区高路堤在地基或堤身不同层位实施换填或处治、施工速率等因素对路堤稳定和沉降的影响进行了计算分析,得到了对生产实际有指导意义的规律的建议.最后对三项实际路堤工程的纵横向变形状况进行了分析.
