摘要
应用复合材料力学原理和层状弹性体系理论对土工格栅沥青路面进行了力学分析.通过对计算结果中的应力、应变和位移分析,揭示了土工格栅的增强机理和防裂作用,同时还计算出加筋可以减薄路面厚度,而且G-AC层模量越大对加筋效果的影响越明显,但是同时也增大了基层底部的弯拉应力,可为路面设计提供参考.
Based on principals of composite material mechanics and plastic layer system theory,mechanical influence of geogrid-reinforcement on asphalt pavement is analyzed. The results of calculation about stress, strain and displacement indicate the reinforcement mechanism and the effect of protect asphalt pavement from cracking. The results indicate that the thickness of asphalt pavement can be reduced. The results also indicate that the higher modulus of G-AC layer are the better the effect of reinforcement, meanwhile the higher modulus can result in greater tensile stress at the bottom of base.The analysis can afford useful reference to pavement designer.
