摘　　要：为了研究拉杆和锚定板对挡墙土压力的影响,利用有限元软件对悬锚式挡土墙进行计算,分析挡墙的土压力分布和水平位移的变化情况。结果表明墙后土压力在挡墙底部有减小趋势,随挡墙高度大致线性增加,锚定板和拉杆的布置越多,水平位移控制的越好。计算结果可为后续施工提供理论基础。In order to study the influence of tie rod and anchor plate on the earth pressure of retai- ning wall, the finite element software was used to calculate the anchored retaining wall, and the change of soil pressure distribution and horizontal displacement was analyzed. The results show that the wall pressure decreases at the bottom of the retaining wall, and the height of the retaining wall increases with the height of the retaining wall. The more the arrangement of the anchor plate and the tie rod is, the better the horizontal displacement control is. The results can provide a theoretical basis for subsequent construction.
