摘要：

Based on the linear bond-slip relationship and the nonlinear bond-slip relationship between reinforcing steel bar and concrete, the calculation model compared with free deformation and the equilibrium differential equations are established for the analysis of the thermal stress in CRCP, the stiffness matrix is also derived based on the contact theory. The distribution law of stress and deformation in CRCP and calculation parameters for crack spacing are analyzed under the thermal load. And it is contrasted with the solution from linear relation. The nonlinear numerical solution of the bar system is also obtained and the bond stress solution is derived. The contact FEM is clear for calculation and the formula provided is easy to analyze the thermal stress in CRCP, it can provide theory for design and research in the future.
