摘要: 分析西部地区县乡公路沥青路面典型结构设计参数的敏感性.通过对路基路面设计参数(结构层厚度和材料 模量)的变化对路基路面工作状态影响的研究,得到路面结构强度随各结构层设计参数变化规律,确定路面结构的 敏感性层位,推荐出设计参数的建议值,为县乡公路土基强度等级划分及路基路面的结构优化设计提供依据

关键词: 敏感性分析, 路表弯沉, 结构层厚度, 结构层模量, 土基等级

Abstract: Sensitivity analysis of the asphalt pavement typical structure design parameters in west county highway Was mainly done.Through the research on the influence of the changes of base and pavement design param eters(1ayer thickness and material modulus)on the highway base and pavement performance,the change rule between the layer design param eters and pavement strength could be found,and the sensitive layer of pavement might be also decided.Recommends the pavement design param eters for the classification on subgrade strength grades and pavement structure design.

Key words: sensitivity an alysis, Surface deflection, pavement layer thickness, pavement layer modulus, subgrade strength grade
