摘要
通过有限元数值模拟,对沥青路面在路基差异变形下的结构响应进行了深入分析,为相关工程设计方法的建立提供了重要的理论依据和技术支持,理论分析表明,较小的路基不协调变形足以使沥青混凝土路面在路面结构中产生较大的附加应力,应力级位明显上升。
Through finite element numeral simulation, this paper deeply analyzes structure response of bituminous pavement under roadbed diffuse deformation, and shows by theoretical analysis that small uncoordinated deformation of roadbed can make bituminous pavement create big additional stress and make the stress grade obviously be elevated in pavement structure, which to offer important theoretical basis and technical support to build engineering design methods.
