目前钢桥面铺装材料仍以沥青或沥青改性为基础，但随着新材料的不断开发研究，铺装材料正呈多样化趋势，铺装层材料参数变化对于铺装体系受力影响分析就成为必要。借助于有限元分析方法，对铺装层材料弹性模量、泊松比、铺装厚度等参数变化对于铺装体系的受力影响进行了深入分析，分析表明，材料的弹性模量、铺装厚度对于铺装层的受力影响较为显著，材料泊松比对于铺装层的受力影响较小，铺装层材料弹性模量、铺装层厚度与铺装体系受力关系存在一个显著转折点，对于铺装层受力规律以及铺装材料设计和选取具有重要指导意义。

The material of Bridge deck pavement of steel bridge pavement is still originated from asphalt or asphalt modifier.However,as the continuous research and development of new materials,vari-ous kinds of paving materials are came into being.As a result,the analysis of influence of the change of material parameters to the load-carrying of the pavement system becomes necessary.This paper by means of finite element analysis,conducted an in-depth research which studied the influence of the change of the pavement layer elastic modulus,Poisson’s ratio and material parameter variations to the load-carrying and stiffness of the pavement system.The research shows that the influence of the elastic modulus of the mate-rial is more significant to the load-carrying of the pavement than the influence of Poisson’s ratio.The ten-sile stress of the pavement increases as the increasing of elastic modulus and Poisson's ratio.A significant turning point exists in the relationship between elastic modulus and tensile stress of the pavement,For pavement stress rule as well as paving material design and selection has important guiding significance.
