广义Gibson地基上的路堤稳定性数值分析

Embankment stability analysis on the foundation of the generalized Gibson

介绍了广义Gibson地基上的路堤稳定性数值计算方法,通过大型有限元软件ABAQUS对其进行了分析,提出了广义Gib-son强度折减数值计算在ABAQUS中的实现途径,并对地基非均质性系数m取不同值进行数值计算分析,得到该地基上的路堤边坡稳定安全系数的变化规律,其分析结果对路堤边坡的设计具有指导意义。

Introduced generalized Gibson soils on embankment stability numerical methods, through large-scale finite element software ABAQUS to analysis, put forward a generalized Gibson strength reduction numerical calculation in ABAQUS way, and the foundation of the heterogeneity coefficient for different values m of the numerical calculation and analysis, get the variation on the foundation of the embankment slope stability safety system, the results of its analysis of guiding significance for the design of the embankment slope.
