Abstract:Crack control of super-long concrete structures is a systematic program that involves three aspects, such as materials, structural design and construction control. The methods of experimental study, field measurement and numerical analysis were adopted to study the key technologies on the crack control for super-long concrete structures. Furthermore, the research results have been applied to a super-long concrete structure located in Pudong Innovation Park of Shanghai Tobacco Group, and achieved good crack control effects. It can provide a reference for design and construction of similar structures.

Keywords:super-long concrete structure; crack control; field measurement; numerical analysis
