| Abstract: | On the base of the mixture principle of the composite material, the distribution and tropism of steel fibre is considered, and the calculate formula of the thermal conduct coefficient, thermal capacity coefficient and thermal transfiguration coefficient is given. The finite element equation of the SFRC pavement plank structure is established with the finite element method. The temperature stress of SFRC pavement plank structure is resolved. The results show that temperature stress of SFRC pavement plank structure is distributed non-linably along thickness direction. |
