利用三维有限元方法 ,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和温度作用下的应力和位移状况 ,分析了反射裂缝产生和发展的原因以及加铺层厚度在防治反射裂缝中的作用 ,为合理设计加铺层提供理论依据。
The stress and displacement of asphalt overlay on the old cement concrete pavement with seams under the action of driving load and temperature were calculated and analyzed by using the three-dimensional finite element method. The reasons for the generation and development of reflective cracks were analyzed, Prevention and control of the role of reflective cracks in order to provide a theoretical basis for the rational design of overlay.
