| 摘 要： | 采用ANSYS非线性有限元程序,分析标准轴载作用下连续配筋混凝土路面横向开裂稳定后裂缝处纵向钢筋的塑性应变,并利用损伤理论及屈服准则推导重复荷载作用下裂缝处纵向钢筋断裂的疲劳公式,具有一定的理论和现实意义。

| Abstract: | Plastic strain of longitudinal steel bar at horizontal stable cracking in continuously reinforced concrete pavement under the standard axle load is calculated by nonlinear finite element analysis program of ANSYS.The fatigue formula of longitudinal steel bar at horizontal stable cracking under repeated loading is derived from using damage theory and yield criterion,which have a certain theoretical and practical significance. |
