Anti-crack Technology for the Construction of Mass Concrete in Dock

This article mainly focuses on the large concrete construction in dock entrance of Bohai Sea ship heavy industry second dock project,in order to avoid the harmful cracks,work out a practical anti-crack technology by processing basically,reducing constraint,controlling temperature,strengthening concrete conservation,and so on.The construction of this project attains good results and guarantees the construction quality.It can provide references for similar constructions in the future.
