随着我国路网改造、老路改建升级,公路桥梁实际承受的负荷出现了交通量增大、重型车辆增加、超载超限现象严重等现象,由此暴露出其结构设计中整体稳定性不足等缺点。如何对桥梁结构进行质量检测评定和加固,提高旧桥的承载能力,确保交通安全已成为管理部门目前和今后面临的重要任务。本文主要探讨双曲拱桥危桥检测和加固的方法。
With the reconstruction of the road network in our country and the alteration and upgrading of the old road, the actual load on the road and bridge has seen the phenomenon of increased traffic volume, heavy vehicles increase and serious overloading and overloading limit, exposing the shortcomings of the overall stability in the structural design . How to carry out the quality inspection, assessment and reinforcement of the bridge structure, to improve the carrying capacity of the old bridge and ensure the traffic safety has become an important task that the management department now and in the future faces. This paper mainly discusses the method of detecting and reinforcing double-curved arch bridge.
