    摘要:

    桥梁基础是将上部结构荷载传给地基持力层的结构,是关系到整座桥梁结构安全的最基本结构。基础工程领域的每一步进展对大跨度桥梁的发展都起着奠基性的作用。近年来,随着中国各种跨海、跨江、跨复杂地质区域大跨度桥梁的建设,在桥梁基础工程领域出现了许多新的研究成果。通过对近年文献的调研,针对桥梁基础冲刷、波浪作用、地震作用、基础损伤评估、地质不良区域基础设计与施工以及既有基础的再利用等几个研究方向,综述了近年来的研究进展,分析和评述了已有的研究成果以及目前存在的问题,并指出基础工程领域研究中需要重视的研究方向和亟待开展的研究课题,对基础工程未来的研究趋势进行了展望。

    Abstract:

    The function of the bridge foundation is to transfer traffic loads to the ground. Thus, the safety of the bridge foundation is essential to the safety of the entire bridge structure. The advances of research and development of bridge foundation engineering are crucial for the development of long-span bridges. In recent years, with the development of long-span bridges crossing wide rivers, deep seas, and poor geological regions, there have been some great progresses in the research on the issues related to the design and construction of bridge foundations in China. In this paper, the research progress and findings in such areas as the foundation scour, the sea wave actions, seismic actions, bridge damage assessment, the design and construction of bridge foundations in the region of poor geological conditions, and the reuse of existing bridge foundations are reviewed and commented. Some major findings in these areas are analyzed and discussed. In the conclusions, the future research trends and some important research issues on bridge foundations, which need to be cared by the bridge engineering community, are identified, to provide researchers and engineers with the up-to-date information on the research ideas that further promote the advancement of the bridge foundation engineering.
