Abstract: With the development of society, more and more super-long concrete structures have appeared one after another. At present, reducing cracks in super-long concrete structures has become a major difficulty. In order to solve this problem, comprehensive consideration should be taken from design, material, construction, maintenance and other aspects. Based on this, this article combines the existing test and construction experience to analyze several important aspects that affect the concrete cracking of the super-long structure, and proposes measures to deal with the shrinkage and cracking of the super-long structure concrete for the reference of the industry personnel.
