为了研究不同筋材刚度对竖直加筋土挡墙工作性能的影响及挡墙力学性能的分布规律,使用有限元数值模拟软件Plaxis分别对砌块式与反包式面板竖直加筋土挡墙进行数值建模,获取可靠的挡墙筋材拉力及面板水平位移数据.研究结果表明:砌块式挡墙筋材拉力及面板水平位移沿墙高方向近似呈梯形分布,反包式面板挡墙筋材拉力与面板水平位移沿墙高呈单调曲线分布.挡墙筋材拉力随筋材刚度的增大而增加,但面板水平位移随筋材刚度的不断增大而减小.除此之外,相比对于砌块式挡墙的影响,筋材刚度对反包式面板挡墙力学性能的影响更为显著.
Effect of reinforcement stiffness on the performance of vertically reinforced re-taining wall
In order to study the effect of different reinforcement stiffness on the performance of the vertically rein-forced retaining wall and the distribution of its mechanical properties,the finite element numerical simulation soft-ware Plaxis was used to conduct numerical modeling of the vertically reinforced retaining wall of the block type and the reverse-cladding type respectively,and the reliable data of the reinforcement tension and the horizontal dis-placement of the surface were obtained.The research results show that the reinforcement tension and the horizontal displacement of the surface of the block type retaining wall are approximately trapezoidal along the wall height,while the reinforcement tension and the horizontal displacement of the surface of the reverse-cladding retaining wall are monotonically distributed along the wall height.The reinforcement tension increases with the increase of reinforce-ment stiffness,while the horizontal displacement of the surface decreases with the increase of reinforcement stiff-ness.In addition,compared with the block type retaining wall,reinforcement stiffness has a more significant effect on the mechanical properties of the reverse-cladding retaining wall.
