| 摘 要： | 主要分析了某一超重荷载(约1 900 t)对沥青路面的影响。文章内容包括超重荷载下路面结构分析及超重荷载运输的费用分配。路面结构分析采用三维有限元法和层状弹性理论程序并结合摩尔-库伦屈服准则进行。超重荷载运输的费用分配则根据超重荷载相对于标准荷载对路面损坏的影响并结合路面大修所需费用进行预计。

| Abstract: | This paper presents a case study of a superheavy load movement with about 1.9-million kg loads on an asphalt pavement.The study included pavement structural analysis under superheavy load and the estimation of cost attributable to the movement.The structural evaluation was performed by both three dimensional(3-D) finite element and the layered elastic analyses with the 3-D Mohr-Coulomb yield criterion.The proposed cost allocation process was based on the predicted damage caused by a superheavy load move and on the estimated cost for repairing the deteriorated pavement. |
