摘　　要：对全国重点文物保护单位广济桥的墩台基础进行加固修缮保护施工,采用基底增加防护圈的方式进行加固处理,基床清淤后利用袋装混凝土填充桥墩掏空部位,用碎石对基床进行整平后,铺设混凝土预制块体并通过卸扣串联形成整体,自下至上抛填一层级配块石,上面铺设土工网格并抛填厚块石,通过互相压实,层层加固的方式提高桥墩基础稳定性,其修缮效果好,安全性能高,对古代桥梁的修缮加固施工有借鉴意义。To protect the key national heritage conservation units Guangji Bridge,researchers thickening protective layer around the base to reinforce the foundation.Firstly,sacked concrete is using to filling the piers’hollowed out section after dredging the river bed.Secondly,laying prefabricated concretes and connecting them in series through shackles after leveling the foundation bed with crushed stones.Last bud not least,throw and fill a layer of graded stones,lay a grid on top,and throw and fill thick block stones.By compacting each other and reinforcing layer by layer to improving the stability of bridge pier foundation.The composite reinforcement method shows a good performance on the repair&reinforcement construction of ancient bridges,which has reference significance.
