FINITE ELEMENT SIMULATION AND STABILITY ANALYSIS ON FLEXIBLE MATERIAL GREEN RETAINING WALL

基于强度折减法,利用有限元软件,模拟研究了不同施工工况下柔性材料绿化挡墙的力学性质及稳定性。经过数值模拟,分析了该新型柔性挡墙土压力的分布规律,以及该类型挡墙内部玄武岩加强筋的受力特点。此外,经分析可知,对于柔性材料绿化挡墙这类刚度较小的挡墙具有足够的安全储备,可在保证挡墙稳定性的前提下,适当减少拉结筋的数量以节约工程造价。

Based on the strength reduction method,the mechanical properties and stability of the flexible material green retaining wall are simulated under different construction conditions were simulated by using finite element software. After the numerical simulation,the distribution law of the soil pressure of the new flexible retaining wall and the stress characteristics of the basalt stiffener in this type of retaining wall are analyzed. In addition,the analysis shows that the flexible material for the retaining wall of such a smaller stiffness of the retaining wall has sufficient safety reserves,can ensure the stability of the retaining wall under the premise of appropriate to reduce the number of drawing bars to save the project cost.
