土工格栅加筋路堤沉降及边坡稳定性分析

Settlement and slope stability analysis on soft foundation valley with geogrid

利用岩土工程有限元软件分析比较了路堤在加筋和不加筋两种情况下的沉降大小、不均匀沉降的分布以及边坡稳定性安全系数计算,指出了加筋能够减小路堤的沉降量和不均匀沉降,提高整体稳定性,减少路堤的变形发展,值得推广应用。

In this paper, by using finite element method of Geotechnical Engineering, the magnitude of settlement , uneven settlement and slope stability analysis are comparedwith two different cases. The first case is the natural foundation without reinforcement and the other is the reinforced soil with geogrid. And by comparison, the significant effects of geogrid reinforcement are discussed. For example, it can reduce the uneven settlement of embankment, decrease its deformation and increase its stability, it is worth spreading.
