| 摘要： | A finite element model for nonlinear analysis of jointed concrete pavements is presented. The model allows for nonlinear representation of the properties of concrete, both in compression and in tension. It also accounts for the behavior under cyclic loading considering the nonlinear fatigue damage accumulation in concrete. An improved model accounting for the relative deformation between the dowel bars and the concrete slabs is presented to analyze pavement slabs connected with dowels. The subgrade model is capable of representing pumping of the fine material with repetitive loading. Limited validation of the model is presented using data available in the literature. |
