【摘要】 基于2种路堤边坡坡比、2种土工格栅和3种加筋层数的不同组合的室内模型试验,比较分析了不同试验工况条件下加筋边坡在顶部载荷作用下的变形规律。结果表明:加筋能较大幅度地提高边坡的稳定性及承载能力;加筋边坡的沉降和侧向位移随着格栅抗拉强度增大、加筋层数增多和边坡变缓而相应的变小。将试验所得结果与有限元数值模拟计算结果进行了对比分析,有限元模拟结果与试验值吻合较好。更多还原

【Abstract】 Based on the small scale model tests,a comparative analysis on the deformation performances of different tests condition for geogrids reinforced/unreinforced slopes were studied,which include the combination of two kinds of slope angles,two types of geogrids and three different reinforcement layers.The results shows that the geogrids will improve evidently the stability and the capacity of the slopes reinforced slopes,Vertical and lateral displacements remarkably decrease with the increase of ultimate strength of geogrid and reinforcement layers and with the decrease of slope angle.Furthermore,a finite element method is adopted to simulate the tests results,the simulated results agree well with the tests results.更多还原
