摘　　要：以某地铁车站深基坑工程案例为背景,介绍了深基坑的设计方案,以及对旁侧并行高架桥梁的保护方案。同时,通过数值模拟,分析了地铁深基坑施工对既有高架桥梁的影响,与现场监测数据进行对比后,验证了数值分析的可靠性。结果表明,该项目基坑开挖对既有高架桥梁的影响可控,设计方案合理。In the case of deep foundation pit in a subway station,the design scheme of deep foundation pit and the protection scheme of the side parallel elevated bridge are introduced.At the same time,the influence of the deep foundation pit construction on the existing elevated bridge is analyzed,and then compared with the field monitoring data to verify the reliability of the numerical analysis.The results show that the influence of the foundation pit excavation in this project on the existing elevated bridge is controllable and the design scheme is reasonable.
