| 摘 要： | 文中基于粘弹性力学理论,采用平面应变有限单元法,分析了温度和车辆加载时间对标准轴载作用下沥青混凝土路表弯沉和加载中心点竖向蠕变应变的影响。得出了随着沥青混凝土材料温度的降低,相同加载时间对应的路表弯沉逐渐减小;随着温度的降低,沥青混凝土路面松驰性能变弱。

| Abstract: | Based on viscoelastic mechanics theory, adopting plane strain finite element method, this paper analyzes the effect of temperature and loading time on deflection of asphalt pavement and vertical strain of loading center under standard axle load. The conclusion is with the temperature decrease of asphalt concrete materials, corresponding deflection go down gradually within same loading time, and with the decrease of temperature, the flabby character of asphalt pavement be weakened. |
