摘要
交通强国建设目标和创新驱动发展战略对跨海桥梁工程提出了新要求,桥梁基础工程作为决定桥梁安全的重要因素之一,其设计、施工及运营维护将面临着新挑战.针对现有跨海大桥基础工程理论与试验研究的不足,系统阐述了国内外跨海大桥基础类型及发展历程.首先,介绍了世界各地典型跨海大桥不同基础的结构形式;其次,对跨海大桥基础的抗震性能、波浪作用、承载性能、不良区域基础施工技术及设计、基础工程耐久性等方面进行了系统分析与归纳,尤其是环境因素与地震耦合作用对其的影响,并指出跨海大桥基础工程研究与实践存在的问题;最后,总结了跨海大桥基础工程理论研究方向和设计及施工技术发展趋势.
The goal of building a strong transportation country and the strategy of innovation-driven development put forward new requirements for cross-sea bridge engineering.Bridge foundation engineering,as one of the important factors determining the safety of bridges,will face new challenges in its design,construction and operation and maintenance.Aiming at the inadequacy of the existing foundation engineering theory and experimental research on cross-sea bridges,the foundation types and development history of crosssea bridges in domestic and abroad are systematically elaborated.Firstly,the structural forms of different foundations of typical cross-sea bridges around the world are introduced.Secondly,the seismic performance,wave action,bearing performance,construction technology and design of foundation in bad areas,and durability of foundation of cross-sea bridges are systematically analyzed and summarized,especially considering the coupling effect of environmental factors and earthquakes.Some problems in the research and application of the foundation engineering of the cross-sea bridge are also pointed out.Finally,the research theory direction of foundation engineering of cross-sea bridges and the development trend of its design and construction technology are proposed.
