本文针对的拉筋问题,目前是我国加筋土结构应用、发展的关键环节。文中介绍了混凝土楔形拉筋及其与矩形拉筋对比试验的结果。由于楔形拉筋对两侧填土产生挤压作用,改善了加筋土结构中拉筋与填土间相互作用的方式,大幅度地增加了拉筋的锚固作用和抗拔力,加强了土、筋的整体性,因而可显著地增大结构的安全度减少拉筋数量,有利于加筋土结构的推广和进一步降低工程造价,具有重要的实际意义。
This article is aimed at the lacing problem, is currently the application of reinforced earth structure in our country, the key to the development. In this paper, the concrete wedge-shaped reinforcement and the results of its comparison with the rectangular reinforcement are introduced. Because of the wedge-shaped tensile reinforcement on both sides of the earth has a squeezing effect, improve the reinforced earth structure in the interaction between reinforcement and fill the way, a substantial increase in the anchorage effect and pull-pull resistance, and strengthen the soil , The integrity of the tendons, which can significantly increase the safety of the structure to reduce the number of tendons is conducive to the promotion of reinforced earth structures and further reduce the project cost, with important practical significance.
