土工格栅加筋技术在公路路基加宽的应用

Application of Geogrid Stiffening Technology in Roadbed Widening

土工格栅加筋技术是一种能够有效的控制路基沉降的施工技术,将它应用于公路扩建中能够降低新旧公路路基的沉降差异,减少公路使用时产生纵向裂缝的机率。首先,説明、新老公路之间的沉降差异及控制,其次,説明土工格栅加筋技术在公路路基加宽的应用机理,最后应用案例説明如何在公路路基加宽中应用土工格栅加筋技术,及应用的效果。把土工格栅加筋技术应用在公路路基加宽,可以发挥它的应用优势,在减少施工资源的前提下优化公路路基加宽的施工效果。

Geogrid reinforcement technology is a kind of construction technology which can effectively control the settlement of subgrade.It can reduce the settlement difference between the old and new subgrade and reduce the probability of longitudinal cracks when the highway is used.Firstly,THE settlement difference and control between new and old highways are explained.Secondly,the application mechanism of geogrid stiffening technology in roadbed widening is explained.Finally,the application case shows how to apply geogrid stiffening technology in roadbed widening and the application effect.The application of geogridge-reinforced technology in roadbed widening can give full play to its advantages and optimize the construction effect of roadbed widening on the premise of reducing construction resources.
