摘要
土工格室柔性挡墙作为一种新型支挡结构,具有结构轻、施工简便,造价低廉、生态保护和美化景观等优势,在公路边坡防护中具有广阔的应用前景。通过有限元软件Plaxis分析了多级土工格室柔性挡墙在不同级数、不同台阶间距和每级墙高变化等工况下的变形特性,得出多级柔性挡墙的水平位移为外凸抛物线形,随着台阶加宽和级数增多,挡墙安全系数变大等结论。
Geocell flexible retaining wall, as a new type of retaining structure, has advantages of light structure, simple construction, less cost, ecological protection and landscaping design, thus may have a broad application prospect in road slope protection. With Plaxis, a FEM software, this paper analyzed the deformation behavior of multilevel geocell flexible retaining wall in different levels, different bench spacing and different height of wall in each level, then concluded that the horizontal displacement of the wall presented an outset parabola and, as the bench widened and the number of level increased, the safety factor thereof improved.
