| 摘 要： | 采用三维有限元静力分析方法,计算分析了具有接缝的旧水泥混凝土路面上沥青加铺层在行车荷载作用下应力随基层模量的变化情况,从理论上深入研究了不同基层模量对沥青加铺层反射裂缝的影响,阐述了基层模量对沥青加铺层荷载应力的重要作用,提出了在结构层厚度一定的情况下,基层最佳模量的取值。

| Abstract: | Adopting the three-dimension finite element static analysis method,calculate and analyse the old cement concrete pavement which was jointed asphaltum overlayer under the wheel load the stress along with the change of the base course modulus,in theory take a deep study of the effect of the different base course modulus to the asphaltum overlayer reflectional crack,set forth the great effect of the base course modulus to the asphaltum overlayer load stress,put forward the best base course modulus when the thickness of the structural layer is definite. |

| Keywords: | reflective crack finite element asphaltum overlayer base course elastic modular |
