摘　　要：以安徽省、江苏省多条高速公路为例,运用回归分析的方法,分析了弯沉盆参数和道路各层模量之间的关系,提出了基于FWD多点弯沉差值的高速公路沥青混凝土路面各结构层状况评价方法,用不同弯沉盆差值来评价面层、基层、底基层和路基结构承载力状况。基于FWD实测弯沉盆数据,验证了该评价方法的可行性和有效性。This paper takes several expressways in Jiangsu and Anhui provinces as example, by meansof regression analysis, the relationship between deflection basin parameters and the modulus of pavement structure is analyzed. The evaluation method for asphalt pavement structure layers conditions ofexpressway based on FWD multi-point deflection difference is proposed, and different deflection basin parameters are used to evaluate the bearing capacity conditions of surface, base course and sub-base as wellas embankment structure. With these measured FWD basin values, the feasibility and reliability of the evaluation method are verified.
