摘　　要：文章利用ANSYS有限元软件模拟研究了旧路拓宽改造时新旧路基不均匀沉降的规律,通过分析公路单侧拓宽和双侧拓宽两种拓宽方式,以及研究单侧拓宽情况下设置不同层数土工格室和挡土墙对沉降值的影响,确定设置挡土墙对减小新旧路基不均匀沉降有较好的效果。In this paper,ANSYS finite element software is used to simulate and study the law of uneven settlement of new and old subgrade during the widening reconstruction of old roads.By analyzing the two widening methods of unilateral widening and bilateral widening of highways,and studying the influence of setting different layers of geocell and retaining wall on the settlement value under the condition of unilateral widening,it is determined that setting retaining wall has a good effect on reducing the uneven settlement of new and old subgrade.
