管窥建筑施工中预应力混凝土施工技术

建筑施工中的预应力是指在承受力超负荷之前采取人为的手段营造应力状态，以这种方式抵消一部分或者全部压力，其中的核心关键点就是混凝土。预防裂缝的产生，相较于普通混凝土，这种预应力混凝土弥补了以往建筑施工中抗裂性差的缺点。

The Prestressed Concrete Construction Technology in Building Construction

The prestressed in building construction means taking the artificial methods to create a stress state before bearing capacity overburden, and ofseting part or al of the pressure by this way, so concrete is the core content. Co- mparing with ordinary concrete, this kind of prestressed concrete wil makes up for the shortcoming that poor crack resistance in building construction.
