土工格栅加筋路堤的有限元分析

采用非线性有限元方法来分析加筋土坡的位移场,可建立五种计算模型。通过有限元分析,对一般土质地基上土工格栅加筋路堤的工作性能进行研究,并对不同布筋方式的土工格栅加筋路堤进行计算与分析,研究各种工况下路堤整体变形情况以及路堤内位移分布、坡面侧移情况。结果表明：加筋能较大幅度地提高路堤的整体刚度和内部稳定性,对地基均匀性和抗变形能力的要求有所提高;加筋路堤边坡的水平位移随着路堤加筋位置的上移而增大。

Finite Element Analysis of Embankment Reinforced by Geogrids

This paper uses the nonlinear finite element to analyze the displacement fields and the stress field in the reinforce slop,creating five calculation models.Through analyzing finite element,it studies the performance of the geotechnical grille reinforced in embankment,calculates and analyzes the different bar arrangement for the geotechnical grille reinforced bar.What＇s more,it studies the whole displacement in every work condition,analyzes the displacement and lateral displacement of the slop in the embankment.The results show that reinforced in the embankment will greatly improve the whole stiffness and the inside stability of the embankment.Moreover,the equality and the ability of the anti-deformation will improve,horizontal displacement in the embankment will be less with the increase of the bar layers.
