摘　　要：通过非线性有限元数值计算,分析了高速公路改扩建路基加宽工程中的沉降问题.采用现场测试工程材料的物理、力学参数,对路基边坡开挖方式、填筑工艺以及加宽宽度进行了模拟分析,得出它们对路基沉降的影响规律.所得结论可为类似工程的设计、施工提供参考.Ground settlement of roadbed widening project in highway extension construction is analyzed by non-linear FEM numerical calculation. Based on field testing of physical and mechanical parameters of engineering materials, the excavation methods of roadbed slop, fill-up technologies and widening width of roadbed are simulated and analyzed, and their influence on roadbed settlement are obtained. The results can be expected to be a reference to similar engineering construction.
