配筋混凝土砌块砌体挡土墙以其安全、经济、方便、节约在美国等国得到了广泛的应用,在我国还处于起步阶段。鉴于配筋混凝土砌体结构具有与钢筋混凝土结构类似的受力性能,本文参照钢筋混凝土挡土墙的设计方法,介绍了配筋混凝土砌块砌体挡土墙的设计方法,并提出了相应的构造措施。另外,配筋混凝土砌体挡土墙在两个边坡支护工程中的应用,表明了配筋混凝土砌体挡土墙作为一种新型挡土墙,不仅受力性能安全可靠,更能节约资源、保护环境、景观协调性好、节省造价。目前,该新型挡土墙正在湖南省长沙至湘潭高速公路(复线)进行推广应用。
Reinforced concrete block masonry retaining wall has been widely used in the United States and other countries for its safety, economy, convenience and economy. It is still in its initial stage in our country. In view of the reinforced concrete masonry structure has the similar performance with the reinforced concrete structure, this article refers to the design method of reinforced concrete retaining wall, introduced the reinforced concrete block masonry retaining wall design method, and put forward the corresponding Construct measures. In addition, the application of reinforced concrete masonry retaining wall in two slope support projects shows that the reinforced concrete masonry retaining wall, as a new type of retaining wall, is not only safe and reliable, but also more economical Resources, environmental protection, landscape coordination, cost savings. At present, the new retaining wall is being applied in Changsha, Hunan to Xiangtan Expressway (double line).
