Abstract: A brief discussion and analysis on the stress calculation of super long concrete structure were conducted. The main factors to influence the intemal and external temperature load of the structure and the design problems were discussed. The mechanics of elastic thermal stress calculation formula were proposed based on the ideal elastic material modification and application.  And engineering practice on the temperature stress calculation for the roof slab of super long structure and reinforcement calculation was given.
Keywords: super long concrete structure; temperature stress
