| 摘 要： | 高速公路的桥梁结构在长期运营状态下会不可避免地出现各种病害,特别是桥台在外界因素和自身作用下会产生裂缝等病害.论文以杨家湾大桥桥台病害的处治方法为案例,通过钢板围带法加固以改善桥台结构的整体性,并且注浆锚杆的实施增强了桥台后方填土密实和固结效果,从而有效保证了桥梁结构的安全运营状态.

| Abstract: | Various diseases are inevitable to occur on bridge structure of highway under a long-term operation status,especially cracks can occur on the bridge abutment as the result of external factors and the internal effects of bridge itself.This paper takes Yangjiawan Bridge abutment disease treatment method as an example,which improved the integrity of abutment structure by using steel plate shroud and enhanced the effect of density and consolidation of fill dirt behind bridge abutment through the implementation of grouting bolt,thereby effectively ensures the safe operation status of bridge structure. |
