h is important to study on numerical simulation of temperature effect in order to prevent the thermal cracking under sunshine. Approximation formula between temperature distribution of single-cell box-girder with 4% single transverse gradient and ambient climatic conditions including air temperature, relative humidity is established based on the test results of Guanyinsha Bridge. Solar temperature effect of bridge is simulated by 3D solid model under cantilever casting construction. It is concluded that calculation results of longitudinal temperature strain are limited by the accuracy of numerical simulation of longitudinal prestressed reinforcement.
