跨河大跨度连续梁桥支架现浇施工阶段地基处理技术

跨河大跨度连续梁桥支架现浇施工时，地基处理的方法及质量直接影响到连续梁桥施工过程中的安全及成桥后的线性。由于跨河支架地基处理没有现成的理论和方法可套用，文章通过施工过程的详细介绍，揭示了该类地基处理施工现场管理与过程控制的基本思路和做法，京沪高铁无锡东桥段中跨越张塘河连续梁地基处理方法和成功经验，不失为一种有效借鉴。

Foundation Treatment Technique for a Continuous Girder Bridge with large Span Cross the River in the Frame in-situ Construction

In the frame in-situ construction for a continuous girder br/dge with a large span cross the river, foundation reinforcement treatment methods and quality directly affect the safety of the construction process of safety and after linear. With no ready-made stent foundation treatment of theory and method, this paper introduces some basic ideas and practices in the foundation treatment construction, management and process control through the detailed introduction of the process of the construction. The foundation treatment and successful experience in the construction of Zhangtang River Wuxi Eastern Segment of Jing-Hu High-Speed Railway can yet be regarded as a kind of effeetive reference.
