摘　　要：近年来,水上构筑物特别是深水大跨桥梁的大量出现使得深水基础施工技术不断发展。深水基础施工平台经历了利用钢管桩单独承力、利用钢护筒单独承力和利用钢管桩和钢护筒共同承力的发展过程。本文以一座公路大桥为工程背景,介绍了大跨桥梁深水基础施工技术及其计算方法,重点介绍了钢管桩和钢护筒共同承力施工平台,为位于江、海及深水湖泊中的大跨桥梁基础及钻井平台的施工与计算提供重要参考。In recent years,the construction technology of the deep-water foundation has been developed continuously since the structures above water,especially longspan bridges over deep-water,appear in large numbers.The deep-water foundation construction platform experiences such a process during which the construction platform uses steel-pipe piles only,steel guide-wells only and steel-pipe piles and steel guide-wells as a support system.The construction techno-logy and calculation method of the deep-water foundation with emphasis on the construction platform for long-span bridges are introduced in this paper,using a highway bridge as engineering background.It is of important reference for construction and calculation of the foundation of longspan bridges and well-digging platform in lake,river and sea with deep water.
