装配式空心板梁桥的运营病害分析及应对措施

Service Disaster Analysis and Countermeasures of Prefabricated Hollow Slab Girder Bridges

梳理了装配式空心板梁桥的主要运营病害,对病害的形成原因从设计、施工、运维等角度进行了综合剖析。提出了改善目前装配式空心板梁桥运营状况的应对措施,需要对铰缝型式及铰缝内钢筋构造进行优化、控制施工质量、对已有病害进行修复加固、科学确定重载车辆的管制措施。

The main service disasters of prefabricated hollow slab girder bridges are summarized and the causes for disasters are analyzed from the perspectives of design, construction and operation. Countermeasures to improve the service condition of prefabricated hollow slab girder bridges are proposed, which could be performed from the aspects of optimizing the hinge joint type and rebar layout in the hinge joint, controlling construction quality, repairing and reinforcing existing disasters, and determining the truck weight control policy.
