肋板式挡墙是由墙面挡土板、摩擦锚固肋板和肋间土体组成的一种新型支挡结构,其稳定性主要受肋板长度及布置间距的影响,为此开展了采用纸质作为挡墙面板和肋板的小型砂箱模型试验。研究结果表明:肋板式挡墙承受的土压力主要通过肋板与肋间土体的摩阻力平衡,稳定需满足肋板最小长度,且肋板长度≥布置间距的基本布置要求;根据不同的肋板布置方式,肋板式挡墙存在长肋疏布的摩擦锚固型和短肋密布的整体土墙型2种典型作用模式;极限稳定状态下,肋板长度≈布置间距的过渡型布置方式最合理,所需肋板面积最小。
The ribbed retaining wall is a new type of retaining structure composed of wall retaining plates, friction anchoring ribs and intercostal soil. The stability of the rib retaining walls is mainly affected by the length of the ribs and the spacing of the ribs. Therefore, Quality Small Sand Mold Model Test as Retaining Wall Panels and Ribs. The results show that the earth pressure on the ribbed retaining wall is mainly balanced by the frictional resistance between the rib and the intercostal soil, the stability must satisfy the minimum length of the rib and the length of the rib ≥ the basic arrangement of the spacing. According to different rib There are two kinds of typical mode of action of the ribbed retaining wall, such as the friction anchor with long ribs and the short rib with the whole earth wall. In the condition of ultimate steady state, the transitional arrangement of rib length ≈ layout pitch is the most reasonable , The minimum required floor area.
