Temperature distribution of one thick concrete box pier under solar radiation is analyzed based on the determined temperature. A mode of temperature gradient with maximal temperature difference is fitted with the exponential function referred to some criteria and formula, and it is significant for studying the law of temperaturt distribution of concrete pier in Guizhou,the design and construction of the same type bridges. Temperature field of box pier is simulated with the finite element program ANSYS. Theoretical results show good agreement with the observations, which means that simulating t...
