摘要
为评估已有800多年历史的南陵县龙门桥性能,对该桥进行了现场荷载试验,并利用有限元分析软件进行分析,结果表明其仍具有良好的短期承载能力,但严重的环向裂缝使得拱圈的整体性和稳定性逐渐降低。从技术、经济及保护文物角度考虑,采用复合拱圈法对该桥进行加固修复,加固后的分析表明桥梁安全储备、整体性和稳定性均有较大提高。
The performance of Longmen Bridge in Nanling county built more than 800 years ago was evaluated and analyzed via static loading test and finite element analysis.The result shows that the bridge still has a good short-term carrying capacity,but the integrity and stability of arches reduce gradually because of the serious ring cracks.The bridge was reinforced and repaired by composite arch method,considering the factors of technology,economy and heritage protection.The reinforcement analysis shows that the safety reserves,and the integrity and stability are greatly improved.
