Abstract:Super-volume concrete construction technique is a special technique in civil engineering at present.Engineers must recognize the basic reasons that restrict the engineering quality of the super-volume concrete in theory.In this paper the causes of temperature stress are analyzed based on a project practice.The detailed calculations for crack control in super-volume concrete construction are carried out.At last,the measures to control cracks in large bulk concrete are expounded,which can be applied in other similar works.
Keywords:pile cap  super-volume concrete  temperature stress estimation  crack control techniques
