摘　　要： 以珠海市S365线井岸大桥主桥加固工程为例,介绍了大跨刚架拱桥增设拱片加固的施工技术,包括施工顺序的选择、桥面微弯板的拆除、新增拱片的支架搭设与浇筑、整体式现浇板的支架搭设与浇筑。实践表明:半幅法施工(增设拱片、现浇面板),不需要大型机械和支架,施工方便,工艺简单,施工过程安全可控,能达到较好的加固效果,为该类桥梁的加固提供了参考和借鉴。 Taking the main bridge reinforcement project of J in g？ an Bridge of S365 Highway in Zhuhai City as an exam-ple ,the construction technology of arch rib reinforcement for large span rigid frame arch bridge has been introduced, in-cluding construction sequence selection,deck micro bending plate removal,the new arch support piece erection stent placement,and the integral cast-in-pla c e slab and erection pouring. The practice has proved ： Demi construction meth-od （arch, cast-in-place panel ）,without the need for large machinery and bra cket,has achieved convenient construc-tion, simple process,good safety control during the construction process,and could achieve good reinforcing re sults, which could provide references for the reinforcing of bridges.
