| Abstract: | How to solve the interaction between the jointed ,multiple-slab system and the foundation in the time domain is an important problem to the non-destructive evaluation in the airport pavements and rigid pavements. Using the finite element method,this paper provides a new method to analyze the reposes of multiple,jointed slabs. With this method, we can solve the response of multiple-slab system subjected to static load or the response of the dynamic system in the frequency domain.Besides,by simplying the foundation to springs and dampers,we can also solve the response of the dynamic system in the time domain. |
