摘要
广西现存最早的木桁架文物古桥—惠爱桥加固设计中,利用同步顶升液压控制系统技术设置主动临时支撑,实现加固过程的主动支撑和节点连接件更换及加固。采用增设永久附加斜支撑结构方法,改善了木桁架结构主要控制截面内力和变形,实现了文物古桥的快速抢险加固,延续和完整保存了古桥的原始风貌,社会效益和经济效益显著。
In the reinforcement design of Huiai Bridge, the earliest ancient timber truss relic bridge in Guangxin province, simultaneous jacking hydraulic control system technique was used to set temporary active brace and to realize exchange and reinforcement of active brace and node connecting components during reinforcement. Permanent additional inclined brace structure was set to improve the internal force and deformation of main control section of timber truss structure, realize emergent reinforcement of ancient relic bridge and complete reservation of original features, producing obvious social and economic effects.
