| 摘要： | This paper presents a finite element model for jointed concrete pavements. 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. Pavement slabs are connected through dowels that are modeled to allow relative deformation between the bars and the concrete slabs and accounts for the effect of repetitive loading on the load transfer efficiency of dowels. The subgrade model is capable of representing pumping of the fine material with repetitive loading. A numerical simulation of the effects of an eighteen-wheel tractor-trailer on the concrete pavement damage is presented. |
