膨胀力作用下的高填路堤稳定性研究

Study on the Stability of High Filled Embankment Under the Expansive Force

基于极限平衡理论,通过室内试验,建立膨胀土物理模型,结合非饱和土五要素重新划分膨胀潜势等级判别标准,利用传统理论推导公式计算边坡稳定系数;运用FLAC/SLOPE软件模拟分析同要素高填方路堤全断面边坡稳定性,对比理论推导公式结果进行验证,具有一定借鉴意义。

Establish physical model of expansive soil through the indoor experiments,based on the limit equilibrium theory,and re- divide the discriminating standard of expansive potential grade with five elements of unsaturated soil,calculate slope stability factors using traditional theoretical formula; simulate and analyze whole section slope stability of same elements of high filled embankment by FLAC / SLOPE software,verified by comparing with the theoretical formula results,which have a certain reference significance.
