| Abstract: | The continuous reinforced concrete slab are applied to the subgrade of Tan Shao Expressway in karst and mined out region. There exists essential distinction between the function of continous reinforced slab and the normal continuous reinforced concrete pavement. So the design method and theory become the key problems of design and execution of continuous reinforced slab treatment of Tan Shao Expressway. This paper introduces three dimensional finite element analysis method to determine basic design parameters of pavement slab, and the employ of double layer layout of longitudinal reinforcement in order to ensure the stability of subgrade in karst and mined out region. |
