为了研究不同土体参数下三级加筋挡墙的稳定性,采用FLAC3D软件对某三级加筋挡墙进行数值模拟分析,分析得出随着土体摩擦角的增大,三级加筋挡墙的水平位移和剪应力逐渐减小,并且减小的幅度逐渐变缓,挡墙的各项性能指标有所改善,加筋挡墙的破坏面形式更接近于Rankine破裂面。
為瞭研究不同土體參數下三級加觔擋牆的穩定性,採用FLAC3D軟件對某三級加觔擋牆進行數值模擬分析,分析得齣隨著土體摩抆角的增大,三級加觔擋牆的水平位移和剪應力逐漸減小,併且減小的幅度逐漸變緩,擋牆的各項性能指標有所改善,加觔擋牆的破壞麵形式更接近于Rankine破裂麵。

In order to study the stability of three-stage reinforced retaining wall, the FLAC3D software is adopted here to analyze the numerical simulation of the wall. Through analyzing the data, the results are obtained that with the increase of soil friction angle, the horizontal displacement and shear stress of the wall would be gradually decreased with the grad- ually decreasing amplitude, and the performance indications of the retaining wall would be improved. Besides, its failure surface would be closer to the Rankine's one.
