摘要
针对不同部位、不同类型的裂缝,提出了预应力混凝土连续箱梁桥的各种相应加固措施及施工工艺要求,并将其中的几种措施应用到一座开裂的大跨径预应力混凝土连续箱梁桥的加固工程中,该桥加固后的荷载试验及两年的运营情况表明了加固方案的合理性。
According to different type of cracks, some strengthening methods of the prestressed concrete continuous box girders of a bridge suffered damages are proposed.Several methods of the mentioned above are applied to a bridge strengthening practise.The reasonability and effectiveness of the strengthening method is demonstrated by static, dynamic tests, and after a period of traffic operation.
