从在土体中加筋提高强度这一概念来讲,我国民间早有运用。自从六十年代提出加筋土作为一种新型支挡结构开始,二十多年来,世界各国相继采用。到目前为止已建造了三千余项工程,最高达43m。施工技术也渐臻成熟。但是,在我国尚处于试验研究阶段,应用于实际工程不多。结合我国具体情况,我们进行了低价材料在加筋土工程中应用的研究。1981年在浙江台州地区建造了两段加筋土工程。系采用工业废钢片和当地出产的毛竹为拉筋,填料是就地开采的砂卵石。
From the concept of strengthening and strengthening strength in soil, China’s civil society has long been used. Since the 1960s, reinforced earth has been proposed as a new type of retaining structure. Over the past 20 years, all countries in the world have adopted it. Up to now, more than 3,000 projects have been built up to 43m. Construction technology is gradually maturing. However, in our country is still in the experimental research stage, not many practical projects. Combined with the specific conditions in China, we conducted research on the application of low-priced materials in reinforced earth projects. Two reinforced earth projects were constructed in Taizhou, Zhejiang in 1981. The use of industrial steel scraps and local production of bamboo is used for lacing, and the filler is sand and gravel mined on site.
