土工格栅加筋作为一种施工手段,使得在非常软的地基上填筑路堤成为可能,通过将土工格栅埋入填土中,依靠格栅与土体的相互摩擦作用以及格栅网眼所具有的特殊的嵌锁、咬合作用,限制其上下土体的侧向变形,改变土体中的应力应变场,增进土的强度和韧性,增加软土路堤的整体稳定性,从而可以有效缩短软土路堤的填筑工期,减少填方量,减少对土地的占用,能够取得较为可观的经济效益。近年来土工格栅加筋发展非常快,被广泛地应用于高等级公路、铁路路堤以及港口的边坡加固和挡土墙的设计。
Geogrid reinforcement, as a construction method, makes it possible to fill the embankment on a very soft foundation by embedding the geogrid in the fill, relying on the mutual friction between the grating and the soil, Has a special embedded lock, bite action to limit the lateral deformation of its upper and lower soil to change the soil stress and strain field, increase soil strength and toughness, increase the overall stability of soft soil embankment, which can effectively shorten the soft Filling embankment construction period, reduce the amount of filling, reduce the occupation of land, to obtain more substantial economic benefits. In recent years, the development of geogrid reinforcement is very fast, and is widely used in slope reinforcement and retaining wall design of high-grade highways, railway embankments and ports.
