摘要：

Taking a two-lane bridge as the background, accurate gradient mode of wall temperature for concrete box girder has been summed up in this paper, based on the comparative analysis between temperature field numerical simulation according to the heat exchange equilibrium theory of prestressed box girder and field measurement. Comparative analysis shows that, this type of numerical simulation of temperature field can objectively reflect the actual boundary conditions with high accuracy, and can meet the requirements of practical design and analysis in engineering well. Then visual module for the analysis of temperature field for pre-stressed concrete is developed, with the same style as ANSYS, taking advantage of second development of ANSYS. Example shows that, the visual module can be well applied in practice, improving efficiency.
