先简支后结构连续的体系转换方式是新建预应力混凝土连续梁桥常采用的一种施工方式。文章结合工程实例,讨论了背景工程的病害情况,提出了进行简支变连续的结构体系转换加固方法在现役梁桥加固中的应用,并列举了T形梁桥的加固实例工程,验证了方法的可行性和可靠性,通过实践利用改变旧桥的结构体系,使老桥重新利用,发挥余热。
The first system of simple structure after the conversion of the continuous conversion of the new prestressed concrete continuous girder bridge often used a construction method. In this paper, the case of the project is discussed, and the condition of the background engineering is discussed. The application of the method of converting and reinforcing the structural system with simple support and discontinuity to the reinforcement of the existing beam bridge is put forward. The example of strengthening the T - Feasibility and reliability, through the use of the old bridge to change the structural system, so that the old bridge reuse, waste heat.
