东平水道特大桥主墩承台钢板桩围堰施工技术

摘要

东平水道特大桥右线主跨286m钢桁拱架桥主墩承台位于广佛交界线东平水道两侧，技术含量高、施工难度大，是深基坑施工的标志样板。钢板桩适应性、互换性良好、时效性较强，可有效缩短工期。本着加快施工进程和提高经济效益，综合分析，权衡优劣的原则，主墩承台采用拉森Ⅲ型钢板桩围堰施工。结合设计与施工，简明扼要介绍钢板桩的设计计算原理，着重详细阐述钢板桩施工操作步骤以及施工中注意的问题，为类似的承台施工提供良好的借鉴经验。%Combined with the design and construction of steel sheet pile, the paper introduced the design calculation principle, mainly discussed the construction steps dealing with steel sheet pile and the attentions in the construction for reference.
