Additional Stress Parameter Sensitivity Analysis of Asphalt Pavement Structure with Deformation Joints in Subsidence Area

提出了设变形缝的沥青路面结构,采用弹性力学理论推导了地表不均匀变形引起沥青路面结构附加应力的解析表达式,并进行了分析.对设缝沥青路面附加应力参数敏感性进行了分析,得出了各因素对路面结构附加应力影响的大小次序,为设计设缝沥青路面结构提供了科学依据.

A new pavement structure, asphalt pavement with deformation joints, is presented in this paper. Based on elastic mechanical theory, a mathematic expression to calculating additional stress due to different settlement is given, and the sensitivity of additional stress parameters is analyzed. It is found that pavement width, different settlement magnitude and pavement base thickness are the main control factor in design.
