| 摘 要： | 采用三维有限元法,分析了重载作用下沥青路面结构应力和弯沉变化规律,研究了沥青路面结构的早期破坏机理,得出在重载作用下,路面结构的表面易产生较大的拉应力,超载将使弯沉和应力急剧增大.结果表明,重载和超载是导致路面结构早期破坏的主要原因.

| Abstract: | This paper analysed the effect of heavy load on deflection and stress of asphalt pavement with 3-di- mension finite elelment method,concluded with the demolishment mechanism under heavy-load and over load. The result indicated that bigger stress appear at the top of pavement,where stress and deflection increase sud- denly,Heavy load is one of the cause which lead to inchoate demolishment of asphalt pavement. |
