摘要
采用８节点等参有限元方法分析了由于软土地基不均匀沉降引起的路面结构附加应力，并在此基础上进一步提出了软土地基不均匀沉降指标限值，以保证软土地基上高等级沥青路面的强度与稳定性．
In this paper,8 point equation parameter finite elements method is presented,and the pavement structure additional stress caused by differential settlements of soft soil foundation is analysed.Consequently,the differential settlements value of soft soil foundation is proposed to ensure good performance of asphalt pavement on soft soil foundation.
