Abstract：
Based on crack resistance of concrete judged according to concrete tension stress at different periods calculated by using the method specified in Code for Construction of Mass Concrete (GB 50496-2009)，To determine incremental temperature difference of center and surface in the heating stage and general temperature drop increment in the cooling phase， Which is at the age of concrete allowable tensile stress condition， may be controlled through analysis on project data and computation model. These results calculated may be used for later temperature control, so as to realize convenient verification and combination between early theoretical calculation and later practical operation. Concrete crack could be effectively controlled.
