海上钻孔灌注桩的施工技术

Construction Technology of Maritime Bored Cast-in-place Piles

海上桥梁地处开阔海域,受海洋气候、潮汐、波流影响十分明显,桥梁基础施工同内陆或内河相比,无论是施工方案、施工工艺还是施工组织方面都有诸多不同之处,本文通过对东海大桥和杭州湾大桥的海上钻孔灌注桩施工技术的研究和总结,为今后海上钻孔灌注桩施工积累经验。

Construction schemes and technologies for maritime bridges differ a lot from those for bridges on inland or across inland rivers due to effect of marine climate, tide and waves. This paper aims to enrich building experience for offshore bored piles through studying and summarizing the construction technologies of maritime bored cast-in-place piles of Donghai Sea Crossing Project and Hangzhou Gulf Crossing Project.
