Concrete is a typical heterogeneous porous media material, but the influence of the heterogeneity of concrete on coupled temperature and moisture transfer is rarely involved in the present numerical methods. Thus, the research direction on the coupled temperature and moisture transfer with damage evolution of the heterogeneous material will be greatly helpful to understand the coupling mechanism. This paper firstly presented the purpose of the study on the coupled temperature and moisture transfer in concrete, and then offered a literature review of the development of this theory. To launch the elaboration of this topic, three relative important parts were presented separately in this paper. (1)The comprehensive theory of porous media heat and mass transfer. (2)The development of the coupled temperature and moisture transfer on mesoscopic scale. (3) The numerical simulation methods of the coupled temperature and moisture transfer. And then the influence of damage on the parameters of temperature field and humidity field was pointed out, which would be a valuable research field.

The penetration cracks in sluice concrete structure have more disadvantage influence on the structure integrity. On the condition of earthquake, it may cause structure collapse. For a typical sluice structure found penetration crack in construction, the finite element model is created and the structure dynamic computation is applied with response spectrum method. The calculation results show if the reinforced steel bar cross the crack is not rusted and destroyed, the tension stress in the sluice and the general safety factor against sliding will meet the corresponding standard. As for the existing cracks, seepage prevention is suggested to avoid steel bar against rust.
