随着桥梁建设向大跨度方向的发展,大型水中承台围堰的施工方法较为繁多,工艺较为成熟。针对不同工程的结构特点,水中大型承台施工围堰形式的选择,将会对整个施工中的安全、工期、经济效益及社会效益有着重要的影响。 With the bridge construction to the development of large-span direction, the construction method of large-scale water bearing platform cofferdam is more numerous and the technology is more mature. According to the structural features of different projects, the selection of the cofferdam for the construction of large-sized water cap in water will have an important influence on the safety, construction period, economic benefits and social benefits of the entire construction.
