有缺陷简支板桥的薄层罩面方法

随着使用寿命的增长和交通量的急剧增加,很多在役简支板桥出现了不同程度的病害。桥头接线道路的拓宽和"白加黑"改造,又要求桥梁同步改造。以合肥市繁华大道跨合九铁路立交桥维修改造工程为例,介绍了在桥梁加固维修的同时,如何实现有缺陷简支板桥"白加黑"薄层罩面的方法,有关经验可供相关专业人员参考。

Thin Overlay Method of Simple-supported Slab Bridge with Defect

With the growth of service life and the rapid increment of traffic volume,many simple-supported slab bridges under service are with the different defects.The widening of bridgehead connection road and the reconstruction of "concrete plus asphalt" road are also required to reconstruct the bridges at the same time.Taking Hefei City Fanhua Avenue Crossing Hejiu Railway Overpass Maintenance Reconstruction Project as an example,the article introduces how to implement the "concrete plus asphalt" thin overlay method of simple-supported slab bridge with the defects at the same time of the bridges under reinforcing maintenance.The relative experience can be referred for the relevant professional members.
