摘　　要：以某道路高填路堤段为例,从使用效果、经济性等角度,对高填路堤方案进行比选,确定采用加筋土方案可达到既节约投资,又生态环保的目的。同时为分析加筋土对路基沉降的效果,建立二维有限元模型,对路基的沉降进行分析。结果表明:在使用加筋土后,道路的竖向沉降明显减小,竖向沉降最大值减少约77%。研究结果可为后续城市道路高填路堤设计提供参考。Taking the high-fill embankment section of a road as an example,this paper compares and selects the high-fill embankment schemes from the perspectives of use effect and economy,and determines that the use of reinforced soil scheme can achieve the purpose of saving investment and environmental protection.At the same time,in order to analyze the effect of reinforced soil on the settlement of the roadbed,a two-dimensional finite element model was established to analyze the settlement of the roadbed.The results show that:after using reinforced soil,the vertical settlement of the road is significantly reduced,and the maximum vertical settlement is reduced by about 77%.The research results of this paper can provide a reference for the subsequent design of high-filled embankments for urban roads.
