摘　　要：应用复合材料力学原理和有限元法对单层和多层土工织物加强沥青混凝土路面进行了力学分析,在行车荷载条件下,研究了不同土工织物层数加筋层数和弹性模量对加筋的沥青路面层底弯拉应力和路面弯沉的影响,以达到优化道路设计的目的。Based on the principles of composite material mechanics and Finite Element Method（FEM）,structural responses of multi-geogrid-reinforced asphalt concrete pavement are analyzed.Under the effect of driving load,several influence analyses were pointed out such as the stress and displacement,with different number of geogrids and different moduluses of the geogrids,so as to achieve optimize road design aims.
