沥青路面各结构层模量对路基顶面弯沉影响分析

Analysis of Influence of Modulus of Pavement Structural Layer on Deflection of Subgrade Top Surface

为研究沥青路面结构层模量对路基顶面弯沉的影响,将沥青路面的结构简化为三层连续的弹性体系,运用弹性层状连续体系的理论分析软件——BISAR3.0,输入沥青路面参数并计算,得到沥青路面路基顶面的弯沉。通过分析得出路基土模量对路基顶面弯沉的影响是最大的,为保证道路结构的稳定,应加强路基土的处理。

In order to study the influence of the modulus of asphalt pavement structure layer on the deflection of subgrade top surface,this paper simplifies the structure of asphalt pavement into a three-layer continuous elastic system,and uses the theoretical analysis software of elastic layered continuous system-BISAR3.0 to input the parameters of asphalt pavement and calculate to obtain the deflection of asphalt pavement subgrade top surface.Through analysis,it is concluded that the modulus of subgrade soil has the greatest impact on the deflection of subgrade top surface.In order to ensure the stability of road structure,the treatment of subgrade soil should be strengthened.
