| 摘 要： | 通过利用Ansys有限元软件对水泥混凝土路面沥青加铺结构的建模分析得出,在其他参数不变的情况下,基础模量越小,加铺层内的等效应力、最大主应力及弯沉值越大,反射裂缝越易产生。

| Abstract: | Through establishing three-dimensional model of asphalt overlay on cement concrete pavement using Ansys finite element programming,it is educed that the equivalent effective stress,maximum principal stress and deflection in asphalt overlay increase with the decrease of foundation modulus in case of the other parameters are invariable,meanwhile reflection cracks are more easy to appear. |
