摘　　要：利用有限元软件ANSYS建立沥青典型路面结构模型并模拟植入加筋体,对不同荷载作用下不同深度处计算求解。对比加筋前后路面内主要应力及变形差别,对主要影响参数利用结果文件中提取的数据及图表寻找规律,以数值模拟结果作为理论实践纽带来指导设计和现场施工。得出模拟加筋后可大大减小沥青路面车辙变形,既增强路面又节省沥青材料,使国民经济受益。The finite element software ANSYS is used to build the structure model of asphalt reinforced pavement and simulate implanting reiforcement to get solution at different load and depth.By comparison of main stress and deformation difference of road before and after reiforcement,find the rule of main effected parameters by the data and charts from the result files.And using the results of the numerical simulation as the ligament of theory and practice,guide the design and construction.The simulation reiforcement can greatly reduce rutting deformation of the asphalt reinforced pavement,which can bring great benefit to the national economy by reinforcing the pavement and economizing the asphalt materials.
