摘要：Setting up post-casting belt is one of the most important measures for temperature control and crack prevention of mass concrete, but current specifications have not given unified and clear rules on the spacing of post-casting belt. In this paper, a 100m long inverted-T shape concrete structure on soft foundation in Yangtze River Delta region is taken as the research object. The temperature and stress field of concrete during construction under different conditions are simulated by finite element method, and bottom plate's and gate pier's recommended spacing of post-casting belt is obtained when poured in different seasons. This will be of guiding significance to the construction of such mass concrete structure.
