白城市红旗街公铁立交桥动静载试验及承载能力评定研究
|
摘要
白城市红旗街上跨平齐线和白阿线公铁立交桥已运营三十余年,存在较严重的病害和安全隐患。通过桥梁检测和动静载试验,对该桥进行了技术状况和承载能力评定,结果表明:主梁刚度和跨中截面承载能力不满足设计要求。
The overpass crossing Pingqi line and Baia line on Hongqi Street in Baicheng City has been in operation for more than 30 years.The bridge has relatively serious diseases and safety hazards.Through bridge detection and dynamic and static load tests,the bridge was evaluated for technical status and bearing capacity.The evaluation results showed that the stiffness of the main beam and the cross-middle section carrying capacity did not meet the design requirements.
