| 摘 要： | 道路交叉口地区的沥青路面由于抗剪强度不足经常出现拥包、推挤、车辙等早期破坏。利用有限元原理对道路交叉口区域沥青路面的破坏机理进行了分析,通过计算揭示了水平力可以大大增加路面拉应力及剪应力水平,并可使路面的疲劳寿命大大降低。

| Abstract: | Shear destructions such as pushes/rut often occur on the crossing asphalt pavements.The destruction mechanism had been analysed by finite method,which disclosed that horizontal load can increase shearing stress and superficial tensile stress of the road surface greatly,and can make the rode fatigue life reduce rapidly. |
