【 摘 要 】

In the subway tunnel construction. Studying the disturbance effects of construction on the surface and underground pipelines requires not only pre-estimation through theoretical and experimental analysis. And more importantly, dynamic forecasting is required through information obtained from the site during the construction process. Dynamic forecasting is of great significance in engineering. Based on the monitoring and analysis of the construction site of the underground excavation section of Shijiazhuang Metro Line 1, this paper studies the settlement curves of surface settlement and underground pipelines. By analyzing a large number of measured data, the empirical parameters applicable to Shijiazhuang area are summarized..
