摘要： 预应力混凝土与普通混凝土相比具有不可替代的应用优势，广泛使用于各类工程建筑之中。然而在高温状况下，预应力混凝土的材料性能会随温度变化而产生一系列不利的变化。对该变化产生的动态机理进行阐述，以期在工程建筑中能够对预应力混凝土技术的推广和应用起到一定的积极促进作用。

Abstract: With the raising of the quality of living standard, citizen's demand on the building environment is also increasingly higher. A residential complex having comfortable and cozy living space and available for different space combinations that can meet different requirements for the entertainment, home working and rest are getting more and more popular. Compared with the conventional concrete, the prestressed concrete has the advantages that cannot be replaced; therefore, it has been widely applied in the building construction. However, the high temperature has an adverse effect on the performance of the prestressed concrete. This paper summarizes the factors that might impact the properties of the prestressed concrete.
