According to the actual mechanical properties of steel bar in continuous reinforced concrete pavement (CRCP), the steel bars were treated continuously, and the orthotropic finite element film model was proposed to verify the applicability of the model. Based on the calculation and analysis of different charge levels, two kinds of critical load positions of CRCP at different crack spacings are proposed. The influence of reinforcement ratio and reinforcement location on pavement load stress is analyzed.
