Prestress Technology and Crack Control of Super-Long Concrete Structure

Abstract

This paper summarizes the causes of cracks in super-long concrete structures. Based on this, advantages of the prestress technology of super-long concrete structure are explained. On the basis of the summary, the prestress technology is the most effective measure. In this paper, the temperature stress and restraint stress are introduced, and the prestress technology is explained, which is beneficial to the application and crack control of super-long concrete structure.
