摘要
以广州地铁某盾构隧道穿越桥梁时桩基托换工程为例,详细介绍了既有桥梁桩基托换施工方法、顶升工法、施工监测等技术应用情况,为在复杂施工环境和复杂地质条件下,进行既有桥梁桩基托换提供技术参考。
Taking Guangzhou subway as the example, where the shield tunnel crosses an existing bridge and the pile foundation underpinning technology is applied. In this paper, the practical application of beam bridge pile founda- tion underpinning construction, jackup method and construction monitorin are introduced in detail, in order to provide certain references of the bridge pile foundation un- derpinning technology for subway constructionin complex environment and complex geological conditions.
