摘要
Abstract
Temperature change and shrinkage are the main causes of cracking of super-long concrete.The influence of temperature difference and closing time of post-cast belt on super long concrete structure is analyzed by using finite element software,and other effective measures to control temperature cracks are introduced.The results show that the greater the temperature difference,the greater the temperature stress of basement roof;Temperature cracks are more likely to appear in the long direction of the structure under the influence of temperature difference.It is an effective measure to control the temperature and crack shrinkage of super long concrete structures to set up the post pouring belt.关键词
