对在深水域中建造桥梁墩身和基础工程提出了管基式沉箱沉井一体化结构的方案,此方案综合了管柱、沉箱、沉井三者的结构特点。提出桥梁墩身基础结构可先在干岸上预制,再浮运到现场就位下沉,再在平台上施工,这样可使工序简化,工程的艰巨性得到缓解,为桥梁的基础和墩身的施工提供了一条简捷的途径。该结构在建造海洋永久性平台、深水码头、海岸水工建筑物等方面也具有应用前景。
A scheme of pipe-based caisson caisson integrated structure is proposed for the construction of bridge piers and foundations in deepwater. The scheme combines the structural features of the three columns, caisson and caisson. It is suggested that the basic structure of bridge piers should be prefabricated on the dry shore first, then float to the site to sink in place and then be constructed on the platform, so that the process can be simplified and the arduousness of the project eased, providing the basis for the bridge and the pier Construction provides a simple and easy way. The structure also has application prospects in the construction of a permanent platform for the ocean, deep-water wharf, coastal hydraulic structures and the like.
