摘要
针对云浮市罗定石溪小桥简支T梁病害特征,根据现有试验研究成果,采用体外预应力技术主动加固,形成双向预应力结构体系,取得明显效果。
Considering the disease characteristics for simply T beam of Luoding Shixi Bridge in Yunfu City, according to the existing results of experimental study, the bridge was strengthened actively by external prestressing reinforcement technology so that could form a two- way prestressed structure system and achieve remarkable resuits, it is worth popularizing in similar projects.
