摘　　要：介绍南康县樟桥(双曲拱桥)加固提载设计与施工以及静载试验实施情况,采用较简易方法加固双曲拱桥,可达到满足现行公路荷载等级标准的要求。其方法特点是加固效果好,施工进度快,加固费用省。Through the introduction of the information about the design and construction aimed at re- inforcing and improving the load of the Zhang Bridge （doublecurvature arch bridge） in Nankang County, and about the implementation situation of static loading test, a more simple method to reinforcement the hyperbolic arch can be achieved to meet the current highway load rating standards. This method is availa- ble for reference to other similar bridges with obvious characterizes in reinforcing effective, fast construc- tion progress and reduced reinforcement cost.
