垂直裂隙对加筋挡土墙稳定性的影响

为研究垂直裂隙对加筋挡土墙的稳定性影响,该文采用OPTUM G2有限元软件模拟垂直裂隙在干燥与饱水工况下加筋挡土墙的稳定性。相对干燥条件下,随垂直裂隙深度的增加,墙后垂直裂隙在饱和工况下,挡土墙安全系数下降显著;随土工格栅长度的增加,裂隙区干燥与饱和条件下,挡土墙安全系数均增大。上述研究结果可为加筋挡土墙的施工与设计提供一定数据参考。

In order to study the influence of vertical cleavage on the stability of reinforced retaining wall,this paper uses OPTUM G2 finite element software to simulate the stability of reinforced retaining wall with vertical cleavage under dry and saturated conditions.Under relatively dry conditions,with the increase of vertical cleavage depth,the vertical cleavage behind the wall in the saturated condition,the retaining wall safety coefficient decreases significantly;with the increase of the length of the geogrid,the cleavage area of the retaining wall safety coefficient increases under both dry and saturated conditions.The above research results can provide certain data reference for the construction and design of reinforced retaining wall.
