文章从混凝土湿热变形、混凝土湿热耦合传输模型及混凝土湿热耦合模拟计算方法等方面进行回顾和总结，详尽分析了混凝土材料湿热耦合变形研究的现状和存在的问题。由于在生产建设与混凝土结构服役期内，混凝土材料与结构受到的季节或昼夜温湿度变化可以用周期性的环境温湿度变化来描述，混凝土变形开裂机理也应考虑“湿热应力疲劳效应”及其损伤演化进行研究。

This paper conducts the review and summary about the concrete from the thermal and drying shrinkage deformation,the coupled heat and moisture transfer model and the coupling simulation method and other aspects, which detailed analysis of the situation on coupled heat and moisture deformation of concrete material and existing problems.Due to the production and construction and concrete structure in service period,seasonal or diurnal tempera-ture-humidity changing of concrete materials and structures can be described by the periodically changing of tempera-ture and humidity.Consideration should also be given to"fatigue effect of heat and moisture stress"when study the deformation evolution and the damage mechanism of concrete crack.
