浮式深水基础跨海大桥结构体系研究初探
|
摘要
随着世界经济全球化发展,沟通洲际之间、国家之间、本土与岛屿之间的大型桥梁工程的建造成为必然趋势。随着跨径的不断增大,海洋深度的不断加大,作为整个桥梁工程的重要组成部分,桥梁深水基础合理的构造设计及有效的施工方案,成为海峡联络大桥建设中首先要解决的问题。本文根据海洋钻井平台TLP和Spar平台的结构型式、受力特点以及存在的问题,引出浮式深水基础这一新型桥梁深水基础的结构体系,并提出研究路线。
With the development of the world economy,the construction of large-scale bridges which communicate intercontinental,national,mainland and islands becomes necessary.With the increasing span and depth of the ocean,the reasonable structure design and effective construction scheme of the deep-water bridge foundation as an important part of the whole project becomes the first problem to be solved.According to the different structure types,mechanical characteristics and existing problems of TLP and Spar platform,a new kind of foundation form named floating deep-water foundation was introduced and the research approach was established as well.
