为了研究路基不均匀沉降对沥青路面受力变形的影响 ,本文通过对半填半挖路基进行弹塑性动力有限元分析 ,计算出在汽车荷载作用下由于路基土在力学和物理性质上的差异而产生的差异沉降。研究了两种工况 (1)汽车荷载作用产生的差异沉降 ;(2 )汽车荷载和土体固结共同作用产生的差异沉降 ,对沥青路面受力变形特性的影响 ,进而得出一种计算沥青路面破坏时临界差异沉降的方法。为实际工程设计、施工提供了理论依据
In order to study the influence of uneven subgrade settlement on the deformation of asphalt pavement, this paper calculates the mechanical and physical properties of subgrade soil under the action of vehicle load by the elastic-plastic finite element analysis of semi- The resulting differential settlement. This paper studies the differential settlement caused by vehicle load in two conditions (1). (2) The influence of the differential settlement caused by the interaction of vehicle load and soil consolidation on the deformation behavior of asphalt pavement, and then obtains a calculation Methods of Critical Difference Settlement When Asphalt Pavement is Damaged. For the actual engineering design, construction provides a theoretical basis
