According to alloying principle,based on the strengthening mechanism during low-temperature deformation and high-temperature deformation,the strengthening model during mid-temperature deformation was drafted.

It is very important to study the thermal deformation occurring in mass concrete and its super-long structures,the cause of which must be made clear before studying the thermal performance of concrete.

The main factors, such as limiting extended value, elastic module and thermal deformation of the influence on crack resistance of mass concrete have been analyzed in this paper.

The main factors,including lim it ing extended value,elastic module and thermal deformation,which influenc on cr ack re sistance of mass concrete have been analyzed in this paper.
