Key Technologies for Reclamation and Substructure Construction at Shoal Location of Sea-crossing Bridges
In the process of sea bridge construction,the reclaimed island and the subsequent works at the shallow beach location face many technical challenges and complex environmental conditions.Taking the construction project of Rim Island Bridge in Abu Dhabi,UAE as an ex-ample,the main construction difficulties are analyzed in depth,and the overall construction process of reclaimed island and the key technology of substructure construction are studied.By analyzing the construction technology of bored piles and checking the pile foundation,the feasibility of this technology in the reclaimed island construction is proved,and the process flow of prefabricated assembled cover girder construction is summarized,which not only reduces the risk of safety accidents,but also shortens the construction period and improves the construction effi-ciency,which can provide experience for the same kind of projects.
