摘要
以某一级公路改造工程中土工格栅应用的实际为对象,采用有限元法建立土工格栅加筋拓宽路基二维有限元模型,分析土工格栅处治路基拓宽差异沉降及加强路基边坡稳定性的效果。
This paper bases on a practical application of geogrids in an actual highway reconstruction project,and the Finite Element Method is used to build the two-dimensional model of geogrids in roadbed widening,which analyzes the effects of reducing differential settlement of widening subgrade and maintaining the subgrade slope stability by using geogrids.
