随着交通量的增加以及荷载等级的不断提高,原有桥梁的病害情况日益严重。以佳木斯松花江公路大桥加固设计为例,详细阐述了针对箱梁顶板开裂这一问题,我们在加固设计过程中考虑的三种加固设计方案,同时为箱梁顶板加固技术的进一步研究提供了切实的借鉴依据。
With the increase of traffic volume and the continuous increase of load level, the disease of the original bridge is getting worse day by day. Taking the reinforcement design of Jiamusi Songhuajiang River Highway Bridge as an example, this paper elaborates the problems of cracking of box girder roof, the three reinforcement design schemes that we consider in the process of reinforcement design, and provides practical solutions for the further research of reinforcement technology of box girder roof.
