摘要: 以福建省某路基工程傍山软基高填方路堤边坡为例,采用有限元软件GeoStudio,结合极限平衡法和有限元法,对该路堤边坡的稳定性进行动态分析,结果表明:该方法在评价傍山软基高填方路堤边坡稳定性上是有效的,尤其是当安全系数临近1.0时,可以结合有限元模拟的应变变形更准确地判断路堤边坡稳定性,为今后类似路堤边坡工程的稳定性评价提供有益参考.Abstract: With one section of a subgrade engineering project in Fujian,the mountain-side soft foundation of high fill embankment as example,by finite element software GeoStudio,which combined with the limit equilibrium and finite element modeling,a dynamic analysis was performed on the mountain-side soft foundation of high fill embankment.The results showed that the method was effective in the stability evaluation of the mountain-side soft foundation of high fill embankment slope,especially when the safety coefficient closes to 1.0,the finite element simulation of the strain deformation can be combined to determine more accurately embankment slope stability,which can provide a reference for the similar slope stability evaluation in future.
