摘要
山区高等级公路建设中,存在大量的高填方路基结构形式,从目前投入运营的山区高等级公路来看,高填方路段的沉降比较严重。采用岩土工程专用有限元软件PLAXIS,对不同高度条件下的路堤沉降变形规律进行深入研究,探讨路堤高度与路基沉降变形的关系。
In building high grade expressway construction in mountainous areas,large amount of high backfilled road bed structures exist,among servicing high grade expressways in mountainous areas,settlement of high fill segments is more serious.This paper uses a dedicated finite element software PLAXIS for geo-engineering,to further explore the rules of embankment settlement deformation under different heights,and discusses relationship between embankment height and road bed settlement deformation.
