浅析沥青路面有限元模型尺寸的选取

Brief Analysis on the Finite Element Model Size Selection for Asphalt Pavement

伴随着沥青路面被广泛用于高等级路面,国内外学者专家对沥青路面的研究,尤其是借助于计算机建立沥青路面模型,对沥青路面进行模拟分析的研究越来越多。然而,沥青路面模型尺寸选取众说纷纭,各不相同。本文通过位移衰减规律进行模拟计算,初步讨论了沥青路面模型尺寸的选取问题,并提出了建设性的意见,为以后沥青路面模型的建立提供了参考。

With asphalt pavement widely used in highways, scholars and experts home and abroad have made some researches on asphalt pavement, establishing the asphalt pavement model especially with the aid of computer to achieve more and more simulation analyses. However, no agreement has been reached on the size selection of the asphalt pavement model. Based on displacement decay laws, this paper carries out the simulation calculation, has a preliminary discussion about the size selection problem of the asphalt pavement model, and puts forward some constructive suggestions, which offers reference for the future establishment of asphalt pavement model.
