摘要
结合工程实际,对浅埋段地铁隧道正上方基坑施工对隧道变形的影响进行了研究。通过建立数值模型分析变形趋势并与实时监测数据进行对比分析,得到了基坑暴露时间对隧道的变形影响规律,并以此对施工方案进行了优化,总结的经验,可为同类工程提供借鉴。
Combined with engineering practice,the influence of foundation pit construction directly above subway tunnel in shallow buried section on tunnel deformation is studied.By establishing a numerical model to analyze the deformation trend and comparing it with the real-time monitoring data,the influence law of foundation pit exposure time on tunnel deformation is obtained,and the construction scheme is optimized.The experience summarized can provide reference for similar projects.
