套拱加固与悬臂拓宽石板拱桥技术研究与实践

Research on reinforcement with arch surround and cantilever widening slab arch technology and its practice

以江西省凤来大桥为例,开展了对石板拱桥这种我国最常见的桥型进行拓宽提载的技术研究与施工实践,另外,对大桥应用到的其他加固技术进行了介绍,以达到拓宽提载石拱桥的目的。

Taking Fenglai Bridge in Jiangxi as the example,the paper has the technological research and construction practice on the slabstone bridge,the commonest bridge to widen and reinforce the loading,and introduces other intensifying technology in the bridge,so as to extend the widening and reinforcement stone arch.
