摘　　要：为研究拓宽路基的变形特性和相应的处置措施,文中采用有限元数值模拟手段对拓宽路基开展数值仿真模拟。结果表明,采用土工格栅对拓宽路基加筋后,能显著改善拓宽路基顶面的沉降变形。增加加筋层数能有效提高拓宽路基的极限承载力,在改善路基变形方面也有良好改善效果。在实际工程中,应尽量由上至下增加土工格栅加筋层数。In order to study the deformation characteristics and corresponding treatment measures of widening roadbed,the finite element numerical simulation method is used to carry out the numerical simulation of widening roadbed,it can obviously improve the settlement deformation of the top surface of widening roadbed.Increasing the number of reinforced layers can effectively improve the ultimate bearing capacity of widened roadbed,and also has a good effect on improving the deformation of roadbed.In practical engineering,the number of geogrid reinforced layers is increased from top to bottom as far as possible.
