桥梁深水基础施工是大型桥梁建造中通常会遇到的研究课题,由于施工环境、结构形式、可利用的设备资源等因素的不同,施工方案和工艺都会有较大差异。该文以万州长江三桥南塔基础为例,介绍了三峡库区复杂地形、水文条件下的特大型桥梁深水基础施工技术,着重阐述了特大型异形刃脚钢围堰在高水位条件下的施工方法。
Bridge deep-water foundation construction is a commonly encountered research topic in the construction of large bridges. Due to different factors such as construction environment, structure and available equipment resources, construction schemes and processes will be greatly different. Taking the South Tower of the Third Bridge of Wanzhou as an example, this paper introduces the construction technology of the huge bridge deep foundation under the complex terrain and hydrology conditions in the Three Gorges Reservoir Area. The paper emphatically expounds the construction technology of the extra large shaped edge steel cofferdam at high water level Construction method.
