摘　　要：空心板梁桥广泛用于中小跨径桥梁结构中,但随着交通运输的快速发展,现役的空心板梁桥受多种因素作用,出现大量病害,其中以底板纵向裂缝最为显著,裂缝出现降低了桥梁的安全性,也降低了承载力和耐久性。论文对纵向裂缝出现的原因进行分析,并提出相应的预防和治理措施。Hollow slab girder bridge is widely used in the middle and small span bridge structure, but with the rapid development of transportation, the existing hollow slab girder bridge is affected by many factors, there are a lot of diseases, among which the longitudinal cracks in the bottom plate are the most significant, the cracks reduce the safety of the bridge, and also reduce the bearing capacity and durability. This paper analyzes the causes of longitudinal cracks, and puts forward corresponding prevention and control measures.
