土工钉主要运用在黄土地区的深沟填筑中路堤与原状土结合处,因黄土坡面常呈陡立形态,根本无法挖结合台阶,很多时候采用的处理方法就是用土工钉来加强结合。确保在填挖交界面上不产生裂缝、结合处不被拉开。文章简要介绍深沟路基在填筑中运用土工钉的施工技术、处理效果。
Geotechnical nailing is mainly used in embankment construction of deep embankment in the loess area to combine with undisturbed soil. Because the loess slope is often steep, it is impossible to dig up the steps. In most cases, the geotechnical nails are used to strengthen the combination. Make sure there is no crack in the filling and dug interface and the joint is not opened. The article briefly introduces the construction technology and treatment effect of the deep groove embankment used in filling construction.
