摘　　要：介绍一种新型重力式多级挡土墙结构。该挡土墙采用的砌筑材料为袋装碎石,即在土工袋中装入碎石后形成的土袋,并将上一级挡土墙墙身自重作为下一级挡土墙的超载进行设计。工程实践表明,该法不仅施工简单、经济效益好,而且为多碎石地区提供了一种新的挡土墙设计方法。In this paper, the structure of a new multistep gravity retaining wall is introduced. The main materials of retaining wall are PE-made bags filled with crushed stones. The design method takes the dead weight of higher retaining walls for its surcharge. The practice of the project used this method shows that this treatment is not only easy to construct, but also has good economic returns. Furthermore, it＇s also a new method for places that had many crushed stones to construct gravity retaining walls.
