摘要: 城市地下通道建设已呈快速发展趋势,但其施工过程对邻近高架桥的影响尚没有十分可靠的理论评价方法,仍需倚重于现场变形监测。在总结分析已有相关桥梁变形控制标准的基础上,详细探讨了地下通道开挖情况下邻近高架桥桥墩变形控制标准的确定问题。首先对现有与高架桥桥墩变形控制相关的标准进行了分析,对周边环境施工情况下高架桥桥墩变形控制标准的现状进行了总结,进而对地下人行通道开挖情况下的高架桥桥墩变形控制标准进行了探讨,最后结合工程监测实例对其进行了初步验证。

Abstract: The underpass in the urban area has a trend of rapid development. But the impact of the underpass construction on the adjacent existing viaduct does not have a reliable evaluation method and the monitoring measurement during the construction is the only solution. After the review of the deformation criteria of the bridges, the deformation criteria of evaluating the impact of the underpass construction on the piers of the adjacent viaduct are discussed. These criteria have been verified during the construction.
