本文依托较典型的空腹式石拱桥加固整治工程,从受力状态着手分析了腹拱圈开裂成因,提出了针对性处治措施,并对加固后大桥的状态进行评估分析,结果表明加固效果良好,为同类型桥梁病害成因分析及加固处治提供了有益的借鉴。 This article relies on the more typical of the reinforced stone arch bridge reinforcement project, starting from the force state analysis of the constriction of the constriction ring arches, puts forward the targeted treatment measures, and after reinforcement of the bridge status assessment, the results show that the reinforcement effect is good, It provides a useful reference for the cause analysis and reinforcement treatment of the same type of bridge diseases.
